Jeff from Boston, MaI have no idea if this is true, but someone told me that Jason Mraz was in the studio working with a group of mostly African-American studio musicians, and felt that the musicians were a little wary of him (Mraz) being a not very cool-looking white guy wearing a pink shirt. On the spot, Mraz began to improvise this song as a joking way of showing them what he could do.
Taylor from San Antonio, Txthis song is freakin great everytime im in a bad mode i turn it on my ipod and im instantly cheered up
"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.
