Yeah, come on. Timbo, A. Keys, let's go! Let me tell you something Tell you how I feel When he comes around I get to feelin' ill It's an achy feeling Inside my chest It's like I'm goin' into cardiac arrest (Bridge) Adrenaline rushin' in my body All my power I just can't fight it No matter how I keep on tryin' I can't deny I got this (Chorus) Heartburn Burnin' in my soul Heartburn Call the fire department Heartburn It's out of control Heartburn You got me trippin', slippin' Gettin' beside myself I tried some medication But don't nothin' help So I say "Doctor, doctor Tell me will I die?" And he said "Count to 5 Alicia" And I'm gonna be alright Let's go! 1,2,3,4 Bridge & Chorus Tastes so good I can't resist Getting harder to digest Can't take no more Gotta shake it off Now break it down And take it to the ground with me now Everybody say oh! Chorus Shake it, shake it, shake it off Go 'head girl Shake it, shake it, shake it off Ooh (repeat)
