Doing hip hop remixes with acapellas, I found one of the best methods for ME to sync, is to lay out the typical bar structure (once I'm *close* to the right tempo) and then make sure that the hook/chorus beginning lines up properly for each one, and that usu. does the trick. You can also tap tempo from the original song on itunes or rhapsody
