Fresh off her performance with Machine Gun Kelly on “The Tonight Show with Jay Leno,” Ester Dean releases a solo version of “Invincible,” which she co-wrote for the Cleveland rapper’s Bad Boy debut Lace Up. The singer-songwriter, who is working on her Interscope Records debut, flips the empowering anthem into a heart-wrenching story of love lost.

“Why can’t I be more like you and cut my heart out, say it’s over, and be done?” sings the raspy-voiced Ester. Feel her pain.
