sentience?

my Rush obsession has come back to bite me in the ass, with a little help from Apple.

i uploaded a double live disc onto my iPod last week. something went wrong somewhere, as that album has replaced several songs. i've found two so far, both different artists. it plays as if it's Rush, but the tag info and duration show up for the "host" song on the screen. i've never had this happen in any other circumstance. just fuckin' weird.
