Breakin'

I think (I'm not sure though) that it's about a girl who's been messing around a guy and basically lying to him a lot.

"Yeah, I've figured it out, girl Breakin's what your heart is for"

• Her heart is made for breaking other people's, like she has done his.

"With every note that you wrote And I hope that you choke On the lines You're wasting my time Another heart beats tonight"

• You lied to me a lot and I hope you suffer for it, you're wasting your time if you're trying to get me back because I'm moving on.
