Chemical Heart

They say you got a chemical heart To try to prove it different is the hardest part They say it's on the tip of your tongue You've been making up excuses since you were young I don't wanna be your babysitter I don't wanna be your five a.m I don't wanna be your Jake LaMotta I don't wanna date your ex-best friend You're standing on the edge of the world You're walking down the street like you're this year's girl I'm calling it a chemical crime You got a lot of nothing but it's mine, mine, mine Singin' nah nah nah, nah nah nah I don't wanna be your Ike and Tina I don't wanna be your remote control I don't wanna be your Bernie Taupin I don't wanna be your stepping stone They say you got a chemical kiss You're breaking down the atoms to get your fix You're looking like a knife in the heart Wishing that it's different is the hardest part Singin' nah nah nah, nah nah nah Have you seen your mother baby sleeping on the floor A permanent vacation crying in the shower stall I don't wanna be your ivory tower I don't wanna be your broken home I don't wanna be your plastic surgeon I don't even wanna walk you home They say you got a chemical heart To try to prove it different is the hardest part I'm calling it a chemical crime You got a lot of nothing but it's mine, mine, mine Nah, nah, nah Nah, nah, nah Singin' nah, nah, nah Nah, nah, nah Nah, nah, nah Singin' nah, nah, nah
