"Fix Incorrect Match" AKA "force upload" option

The only thing you can do is remove the songs from your library, give iTunes time to resync, then re-add them. I've heard from some people who told me that songs that weren't matched before are now matching with the latest iTunes update.

Ah, right, mis-matches. Unfortunately, you are, as they say, screwed.

Digital remasters should be "different." The audio is different enough that I would expect it to be differentiable. Unless the remaster simply has volume changes, rather than changes to the mix, in which case I doubt that audio fingerprinting notes any difference (since you could have manually changed the gain on a file). But iTunes Match also mixes up live and studio versions of songs, which suggests that it's not just digital fingerprinting, or perhaps these are problems in the iTunes backend database.
