I am "lucky" to be one of the new iPhone 5 owners, after switching back from two years with android. Part of the reason for my switch was iTunes Match, which has been a constant confusing dissappintment.
After several iPhone restores, lengthy phone calls to Apple support (who had no idea what to do), I am still stuck as to what is going wrong with my iPhone and its syncing between itunes match and my local (mac) itunes.
Essentially, I understood (both from reading online and apple support) that I could turn match OFF on my iphone, and then sync playlists accross from my Mac. Then, I could turn my iPhone's Match ON, and it would warn me about replacing the library, but it would allow me to play my synced playlists offline, and stream the rest of my cloud music. I was somehow using this method for a few days, before today's sync changed things again. (I didnt change settings)
At this current stage, itunes match is enabled, and my computer has just finished syncing with my iphone. My iphone says it has no locally stored songs, the computer says my iphone has 19 locally stored songs (with match enabled.) I have tried various ways of syncing, enabling and disabling match on my iphone, and no combination i have tried has successfully synced my data accurately.
Side note: Apple also didnt know why after the second sync between my iphone and mac the mac song playcounts changed dramatically. (ie: from 120 plays per song to 700+ plays - And i hadnt played them obviously).
Note: All software is up to date. Screenshot here http://cl.ly/image/0y162Q2C1c2w shows status after fresh wifi-sync. (incorrect values for free space etc)
I am trying to sync playlists from my mac to my iPhone 5, and then have my iphone stream/(download) the rest of the music I dont sync across through iTunes Match.
It seems there are some bugs in iTunes/iOS 6 to do with syncing. iTunes displays different information about my iPhone, to what is in the iPhone's settings menu. EG: Itunes says there are 19 songs on my iphone, my iphone says there are no songs on it.
This sounds like a bit of a ramble, but its one of the more important issues/problems i am having with the new iPhone. Hope someone can help, or has advice!
