If you went into MGMT's sophomore album, Congratulations, expecting another batch of tripped-out pop songs, chances are you were infuriated. The band went into recording this project with the intent of delivering something different, fresh, and entirely new, which they most certainly did. But as we noted, turns like this aren't going to met with open arms.

A few critics might have embraced the album, but fans were more reluctant to do so, leading MGMT's Ben Goldwasser to even come out and apologize for lead single "Flash Delirium."
