X&Y Syndrome 

X&Y Syndrome is a disturbing but temporary disease. X&Y Syndrome comes when a listener to an album dismisses the album for any reason, then re-listens to the album they dismissed, and loves it.

Matt: Yo, I'm not the biggest fan of X&Y by Coldplay, there's only a few good songs on it
Joe: Alright man

*Three Weeks Later*
Matt: Joe! I re-listened to X&Y and I love it! What was wrong with me when I dismissed it for the first time?
Joe: Damn dude, I don't know!
Matt: I'm gonna name this thing... X&Y Syndrome.
