This dreamy ballad features Atlanta rapper Future and samples Aaliyah's version of The Isley Brothers' "At Your Best (You Are Love)."
"I'm definitely a fan of Aaliyah," said Braxton of the late songstress. "She was one of my good friends because her uncle [Barry Hankerson] and my sister [Toni] were affiliated at the time, so I spent a lot of time with her."
The original version by The Isley Brothers was dedicated to their mother and was a radio hit for them in 1996. Aaliyah's revival was released as a single in 1994 peaking at #6 on the Hot 100.
Canadian rapper Drake also sampled Aaliyah's version of the song in his 2010 cut "Unforgettable."
The song was included as a bonus track on the Walmart deluxe edition of Calling All Lovers.
"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.
