I love that song..didn't know it was Ashlee's song until now.
I agree with BlueReign that it's best heard live. If it were to go national, it would have done so by now.
But Go-go has always sampled from pop songs. Case in point, one of the bands sampled Sisqo' Thong Song and it was HOT
Go-go has also sampled some west coast songs that were good too.
