This is a track from Wake Up!, a collaborative album between R&B musician John Legend and Hip-Hop band The Roots. Inspired by the 2008 United States presidential election, Legend and The Roots primarily covered 1960s and 1970s soul music songs for the record.
This song was originally recorded by Mississippi singer/guitarist Ernie Hines. Though obscure, fans might recognize it from a famous Hip-Hop sample used on "Straighten It Out" by Pete Rock & C.L.Smooth. Roots drummer ?uestlove told MTV News: "People might not know 'Our Generation,' but there's definitely people in their mid-30s that know Pete Rock & C.L. Smooth 'Straighten It Out.' And it will also hit people that knew the original 'Our Generation,' that are now 50 years old."
"Kickstart My Heart" is about all the ways Motley Crue gets their blood flowing without drugs. It was inspired by their bass player Nikki Sixx, who claimed he had to be revived with a shot of adrenaline to the heart after an overdose.
