There's a controversy around this track. It's credited to Bob Sinclar and it's on his Paradise album, but it actually a collaboration with Thomas Bangalter. It's been theorized that he disassociated himself from it after Jane Fonda, whose voice was sampleled from her famous '80s workout videos, wouldn't give them the rights. Sinclar puled a YOLO and put the track on his album anyway, but Bangalter prefered to have nothing to do with it.
