I just found a completely wrong album cover for an in-game track. If you go and check out "Seasons" by The Veer Union (off their album, "Against the Grain"), look at the album cover provided. That's the wrong album cover; it is, in fact, the album cover for Bad Religion's album of the same name. Take a look at the Amazon page for "Against the Grain" by The Veer Union, and you'll see what the actual album cover should look like.
On a side note: Has anyone else noticed any wrong album covers in-game? This just seems really hilarious to me.
