I picked PJ Harvey specifically because it's a new release, but also because I've heard the CD version and the sound differences between the two are hard to distinguish assuming the few pop/clicks are removed. And this is of interest because the match % on that one was very high for me. I still think masterings are a critical component to the matching process.
My best match, all tracks but one, is Jaco Pastorius' self-titled. Only Opus Pocus, track one on side two, didn't make it through. I've noticed it seems as though songs that make it through are in groups, then one doesn't make it, then groups again. I'm wondering if in some cases being the first or last track on a side is significant. Outer and inner tracks are more susceptible to certain kinds of wear and damage.
Also, another factor to keep in mind as far as your TT - pitch control..
True. My Dual is an idler wheel. I use a strobe disc to dial it in, but admittedly I haven't been as religious about checking it as I should. I do think getting pitch as close to what Apple's using as a baseline is probably a significant factor in getting a match. I've read of people who knew the vinyl they had was mastered at the wrong speed, something that was corrected when it went to CD. In those cases, a match might require being able to adjust your playback pitch to approximate the CD correction - something I can't imagine having the patience for.
Here are the results of some of my vinyl matches.
Art Tatum - The Essential Art Tatum 7, 9 (this disc is in bad shape so I was surprised even two made it)
Billy Holiday - Lady In Satin 11, 12 (also in bad shape, so bad I haven't recorded the A side, so two out of six I submitted made it)
Bob James - Bob James Two 2, 4, 6 (50% match)
Buckingham/Nicks Nothing matched, but I'm not sure it's in the iTunes store
Chick Corea - Eye Of The Beholder 1, 3, 4, 5, 9 (there are variations in track order between vinyl and CD, songs on CD not on vinyl (or vice-versa, forget which)
Classics IV - Spooky 11 - so it matched the title track, which is probably somewhere on the store, but I don't think the actual album's available.
Creedence Clearwater Revival - no matches. Fine, with my luck I'd get the short version of SuzyQ which really isn't SuzyQ at all.
Dave Brubeck - Greatest Hits 5, 10 Again, most likely songs available on other albums and in the store.
Dave Brubeck - Time Out 1, 3, 4, 7 I've got three copies on vinyl of this one, so it's probably a good one to experiment with.
David Crosby - Wind On The Water 1, 2, 3, 5, 6, 7, 8, 9, 10, 11. Didn't realize this matched all but one until I looked. My copy is M-, but that in and of itself hasn't been enough to get other albums to match so well.
DIane Schuur - And the Count Basie Orchestra 1, 2, 3, 6, 7, 8, 9. This is a digitally mastered album I got still sealed. My guess is others she did around that time would match too - if they were in the iTunes store that is.
Donovan - The Hurdy Gurdy Man 1, 5
Earl Klugh - Heartstring 100% match
Issac Hayes - . . . To Be Continued 0% match. Tuneup has subsequently pointed out that the title on my copy was wrong (missing three periods). It's one on the list to fix and resubmit.
Madonna - True Blue 100% match
Miles Davis - Amandla 1, 2, 3, 4, 8 Recorded from a pretty clean white label promo
Peter Gabriel - Peter Gabriel 2, 5
Peter Gabriel - Security 3, 8
Peter Gabriel - Sledgehammer (maxi-single) 3, 4
Ray Lynch - Deep Breakfast 0% match
Rush - Hold Your Fire 100% match. One of the few albums I captured at 44100. Most are done at 96, but downsampled to 44100 when exported from Audacity.
Spencer Brewer - Emerald 7
Steely Dan - Aja 3, 6
Van Morrison - Moondance - matched all but last track on Side B
Van Morrisson - A Sense Of Wonder - Matched only track 1 Both Morrison albums were recorded in the same way and the one that matched was in worse shape than the one that didn't.
Vangelis - Direct 1, 2, 3, 6, 7, 9
Newport Jazz Festival All- Stars 0% match - may not be in the iTunes store.
William Ackerman - Conferring With The Moon 5, 8
I also have converted from vinyl a multi-disk compilation "solid gold party rock" Not in the store, but a good example of how iTunes may or may not match something if it's found on another album. I'd say I got a 40%-%50 match on that one
