As Politico points out, the record, Songs for a Healthier America, is inspired by the First Lady's Let's Move! campaign. It includes cameos by video and in the form of audio from one of her speeches, but she doesn't "sing" on the album.
Matisyahu, Ashanti and others appear on the 19-track set. Ten related music videos are also set to be released to schools in New York and other cities.
