Mass appeal????? damn dude, Britney spears has mass appeal. Any song which is more complex that a 4/4 ABACADA structure is going to be pretty hard to sell, specially nowadays.
they might make it slightly bigger than they are at the moment, but i dont think they'll make it BIG.
its a shame. it takes much more brains and effort to put together something like Stupid dream than it takes to sing 5 notes and shake your ass...
