“Burnin' Up” is a R&B-influenced collaboration with rapper 2 Chainz. It’s an uptempo love song that uses fire as a metaphor for lust.

The song details the way Jessie’s partner makes her feel, and how when she’s with him, he makes her feel on fire, meaning on top of the world, and she is calling out for him to “put [her] out” which could be a metaphor for her need for sex.
