Cee Lo Green is one of the marquee names on the upcoming soundtrack for 'Grey's Anatomy,' the fourth soundtrack for the medical drama television show since it began airing in 2005.

Green's contribution is 'Old Fashioned,' a song which also appeared on his album 'Lady Killer.' 'Old Fashioned' fits its title with an old-time soul vibe. 'The Voice' coach's music has been popping up all over the place this summer, as he also recorded a song for the Buddy Holly tribute album, and sang on the soundtrack for the 'Footloose' remake.

Other artists on the 'Grey's Anatomy' album include indie favorites the National, Peter Bjorn and John, and Lykke Li. The soundtrack is the fourth in the 'Grey's series, not including the 'Music Event' EP that hit iTunes earlier this year. Previous editions in the series featured hits like Snow Patrol's 'Chasing Cars' and the Fray's 'How to Save a Life.'

The soundtrack drops Sept. 13 on Chop Shop / Atlantic Records. Check out the full tracklisting, courtesy of Billboard.
