Con-Track

When a band/label release a song which is not representative of the album it is from.

Guy: "hey dude did you hear the new Fictus track on the radio? it's awesome, i'm gonna go buy the album right now!"

Me: "don't bother, it's a Con-Track, the rest of the album is crap and sounds nothing like it"

Guy: "oh. that's extremely disappointing"

Me: "indeed"
