We get it: You're feeling vaguely depressed now that March Madness is over. Is that sports-related bipolar disorder? Hey, we're no doctors. But maybe the cure for what ails you is moving directly to baseball. Check out this new MLB spot featuring the rousing tune "The Great Unknown" by Cherrytree/Interscope's Jukebox the Ghost.

The band's single "Postcard" impacts AAA radio on 5/2, and the band will join Ingrid Michaelson on an amphitheatre tour (including L.A.'s storied Greek) this summer. Look for an official vid soon.
