How does iTunes Match work with live and acoustic versions of songs, if I also have the album version of the same song. I'm a little concerned that it may try to overwrite my live copies with the album ones. I've noticed often when just listening through my playlist and having it on shuffle, it will play the album version immediately followed by the live/acoustic version. It's as if the system gets stuck on the song name, and doesn't distinguish between the two. Any thoughts?
