A number of people have found that iTunes Match sometimes matches incorrect tracks; not that the songs are wrong, but that the versions might be wrong. This seems to happen especially with music that has been remastered. iTunes may match either an original or remastered track, and the user who matched the track may have tho one that iTunes doesn’t have. This can be a problem, if, say, you prefer an original album over a remastered version, or vice versa.
But I today I found, for the first time, a bad track coming from iTunes Match, one with an audible problem. It’s one of an excellent set of Bill Evans recordings, The Last Waltz, from the summer of 1980, just before his death, made at the Keystone Korner; the song is Your Story, While iTunes matched these tracks, I was listening to some of this music today, and found a bad track. There’s a gap of about a half-second at one point in the track. Looking at it with Rogue Amoeba’s Fission, you can clearly see the missing chunk of music:
If this happens, you’re basically screwed. Who can you complain to? Contact the iTunes Store? I doubt anything will happen. The only way to have a good copy of the track is to take your original and make sure it stays in your library; if you ever have to download it again, you’ll get the track with the gap. It’s worth noting that this track is not available on the iTunes Store. This makes me wonder exactly how they match such tracks; do they match them to tracks that other people have uploaded?
I don’t expect this will happen a lot, but the fact that it happens at all shows the weakness of this system. iTunes Match clearly needs an option for tracks that you don’t want matched, ones that you want uploaded, because the matched version may not be the same as yours.
Has anyone else found matched tracks that have similar problems?
(As an aside: if you like Bill Evans, there are two box sets of this run at the Keystone Korner, in San Francisco, between August 31 and September 8, 1980. The Last Waltz is music from the first sets, and Consecration has tracks from the second sets. Just a week before his death, Evans was playing some of his finest performances. These two box sets, together with Turn Out the Stars, recorded at the Village Vanguard in June, 1980, comprise 22 discs of astounding piano music.)
Update: my son came across a bad track today. It’s a match of Philip Glass’s Witchita Vortex Sutra, from the Minimal Piano Collection box set. There are clicks throughout the track, with one big dropout at 4:25:
