A couple years back my iTunes library went a little corrupt. I've got a few songs on various artist albums where The next song/artist title is the same as the one before it. Also some other artist's songs are incorrectly tagged as on a different album. I've fixed a few here and there but it's so random that I've never been able to fix the issue entirely (nor can I catch most of them). I ask this because I'm thinking iTunes Match may fix this problem. I mean how else will iTunes decide which songs you have if it doesn't scan each one? Otherwise you could just get a song that's the same length as a different song and fill out the metadata for it and iTunes will think you own music that you don't, no? I don't think it will do it that way, so what happens when it finds a song that is incorrectly tagged? Will it fix it for you? That could be a big plus.
