I signed up for iTunes match today, which is pretty cool. However, on two (that I know of) of my albums it did weird stuff to the metadata that made it split up. On one of the albums, it singled out one song, gave it a different track number, and made it part of a compilation. Afterward, on my phone it looked like two albums. This was an album I purchased from iTunes as well, and I had not altered the metadata in any way. I tried changing it, but when I updated iTunes match, it reverted to the strange metadata. Any ideas? Edit: I managed to fix it. For the purchased song, I deleted and re-downloaded. It still had the affected metadata, but I fixed it. The key was to not hit "update iTunes match" right away. For the other album, I deleted the album, reimported, made sure the metadata was right, and updated iTunes match.
