    I don't really have use for iTunes Match as a cloud storage solution. I'm looking more to upgrade my music collection. All my songs are 128kbps mp3's becuase when I got my first 10GB iPod almost 10 years ago, I was trying to fit as many songs as possible on. Then I just kept ripping at the same bitrate for continuity sake. I'd love if iTunes match would work for me as an easier upgrade than re-ripping hundreds of CDs.


    @AndreGB, Please let me know how this works for you. If it matches songs that arn't in your store I may also give it a try and see if it works for me.

    I'm in the same situation - the cloud storage is nice, but the matching portion is what sets it apart from Google/Amazon and its the main reason why I coughed up my 25 bucks for my year subscription.


    I'd also like to know how this turns out for non-US customers - I can obviously only go on my situation in the US, but hopefully you'll have the same benefits as what i've seen with matching.

    Sorry - I just saw your question - I turned match off and then back on the iPhone and it seemed to cure almost all of the bad links. Bascically my problem was that if you selected tune A in iTunes another song would play. So far the results have been worth the problems because my mp3's are much better after matching. I woudl like to see some better, easy to find, information from Apple.

    I'm a new UK Match user... Out of some 13,351 eligible items, only 2,535 have matched. That's a hit-rate of less than 20%. Been uploading for two nights in a row, but it uploads about 400 songs per night. So at this rate it'll be about a month before I've uploaded everything...!



  • nick ashley Level 1 Level 1


    When you say only 2535 matched... have you let it run to completion yet ?    I had about 8000 (of 11000) match straight away... a good proportion of the others seemed to just want to upload artwork - so had a status of "Waiting".    Some of the remaining 3000 (maybe 800-1000) did need a full upload but others just didn't and sorted themselves out during the "upload process".

  • Jowie Level 2 Level 2

    No, it's only uploaded about 1000 songs so far... This is the third night I've run it, and I'll have to run it for a further four weeks of nights before it finishes! But ever since the beginning of the upload process, it's not changed from 2535 matched songs.


    It's already done the "Match" part of the process, so it doesn't seem particularly likely that it'll match any more during the "Upload" part?

  • nick ashley Level 1 Level 1

    Well mine did more matching yesterday (i.e. it was uploading ... but just artwork.... for some songs) ... today is taking longer.  


    Latest stats 11158 songs.   

    9752 matched

    732 uploaded

    4 failed

    684 remain pending


    .. the numbers don't quite add up but I don't know why.

  • Jowie Level 2 Level 2

    I took my HD into work to use the nice fat pipe we have there, and now I'm nearly done! But the number of matched songs has only gone up by one...


    My stats so far for 13,140 Songs are:


    2,536 Matched

    339 Purchased

    9,651 Uploaded

    191 Duplicate

    114 Error

  • nick ashley Level 1 Level 1

    Jowie - that is not a good rate for "Matched".


    Some things that I have noticed :-


    1. It is not good at matching special edition CDs, Boxed sets , remixes etc.

    2. It is not good at matching audiophile CDs e.g. I have David Bowie (Hunky Dory) but in an audiophile Au2O CD. 

    3. It does not seem to matter whether you rip to mp3 or AAC (at least in 2. above).


    I still have 682 songs to upload (not a good day yesterday).  The problem is that my ISP limits uploads - because of P2P .. but this catches out itunes match uploads too.

  • Jowie Level 2 Level 2

    I think if anything, my CDs are probably too old-skool for iTunes... In that a lot of them are pre-remastered versions from the early 90s. Perhaps this is a reason?


    I've still got a fair few songs that say "Waiting", even though iTunes Match says it has finished. I tried "Update iTunes Match" from the Store menu, but they still haven't uploaded.

  • roebeet Level 2 Level 2

    It's very possible about the older masterings and I agree with everything Nick has written.   Apple's matching threshold is such that any slight deviation in sound could affect it - be it a older master, or pitch (the latter being something that affects things like vinyl recordings).    I personally feel that the masters need to match to get a good match in iCloud.

  • Jowie Level 2 Level 2

    I wonder if it is also due to the fact that since I have been re-ripping old CDs, that the discs have faded enough that the error correction has stopped them being recognised by iTunes Match...

  • Mike Connelly Level 4 Level 4

    If the discs still sound fine, very unlikely it's an error correction issue.  My guess is that older discs have likely been remastered since then and have slight differences in things like track length.  Apple either needs to loosen up their matching algorithms or add alternate pressings to their database.

    OK, so I've enabled iTunes Match and had some really interesting results. But first, @MVallee I've had matched songs there were neither on my country's iTunes Store and neither on the US store. I didn't look any further to find out where those songs are available, though.


    Now, I had aproximately 2300 matched songs out of 4000 on my library. There are several albuns which had a mix of upload and match as well, like all of you. There is one thing interesting, though. When I was living in the US, I had a chance to purchase several songs and complete albuns from the US iTunes Store. Since I am currently not there, I have activated iTunes Match on my country's store, it means that the purchased songs from the other account had to be submitted for analysis. Guess what? iTunes has uploaded (or, not-matched) several iTunes-downloaded songs. This is it. This is the ultimate test for me. It shows me that the iTunes Match algorithm is not really accurate yet, or it is too tight since it is not matching songs downloaded from iTunes itself. It sort of proves as well that if iTunes is using the music length and metadata on the matching process than these don't have an important weight on the decision right now. You would say that these songs have the perfect match on the duration and metadata, right? I have sereval iTunes downloaded albuns that didn't match completely, it was always 1 or 2 songs that got uploaded.


    I have a friend researching audio technologies at the University and I had a chance to talk to him about this service, which he got really interested. He said that if iTunes is getting random samples from the music file, it is very possible that iTunes is getting hard to match bits from some songs. The easiest and most accurate way of matching songs is on vocal segments. This is what Soundhound suggests too, that you sample a part of the song that is sung. He also said that it is possible that iTunes is getting very small samples from the songs, what could make it even harder to match. And the reason for that is the complexity required for matching longer samples which would tax and possibly crash Apple servers. Soundhound would take a 15 seconds sample which, in his opinion, is VERY good for matching already. However, Soundhound tries to match only one song at a time from each user, while iTunes is trying to match whole libraries against their own library. Increasing the "sample duration" could have an exponential increase of complexity on Apple servers (depending on the method they use for that) which could make it impossible to handle all the new users requests. Well, he obviusly don't know details on how iTunes Match works behind the scenes, but if they are matchings samples themselves (the most accurate method) than these are the "rules". He only wishes that Apple increases the sample duration once the request for matching whole libraries (new users) drops, so we can have better matching. In that case, my question remains. What happens to songs that were already analyzed and either matched or uploaded? Would they have a second chance and change from uploaded to matched?


    Thank you all.

    Actually, no, that's not what your results mean.


    When you activate iTunes Match with an iTunes Store ID only that store's content is scanned against your library. iTunes Match does not scan cross-store. More specifically, if you have an account in the U.S. iTunes store and activate iTunes Match against that account then that is the only store that will be scanned against your iTunes library. If you have tracks in your library from, say, the U.K. iTunes store those tracks are not eligible to be scanned against the U.S. store and will instead be uploaded, as long as your computer is authorized to play those tracks.
