"We just really like to play music," MGMT singer/guitarist Andrew Vanwyngarden said Sunday night at New York City's Mercury Lounge, where his five-piece band unveiled their second album, Congratulations, with a secret gig. He wasn't kidding -- and it showed.

This week MGMT leaked a new song, the Strokes confirmed a September album release, and SPIN remembered the Notorious B.I.G. 13 years after his murder. Meanwhile, Lady Gaga unveiled her epic new video, the first trailer for Twilight: Eclipse hit the web, and the Smashing Pumpkins began their search for new bandmembers.

It's a good day to be a fan of MGMT.

The Brooklyn psych rockers have just released "Flash Delirium," the first leak from their much-anticipated second album, Congratulations, out April 13. Head to the band's website to download the track! (NOTE: This link may expire at any moment.)

Mark your calendars, Blackberries, iPhones, iPads, or just write it on your damn hand -- 'cause now it's officially official: MGMT's second album, Congratulations, will release in the U.S. on April 13.
