Didnt Aerosmith do a song for a movie..thats highly commercial. I think bands eventually give in to the commercial end of things at some point or other...everybody has to pay their bills. You do what you have to do I guess. Besides I dont think ppl work their asses off on something to have it fail,so if going out and promoting it to death or going somewhat commercial gets you into ppls minds then I dont really care. As far as their writing goes, I think its what they know and they stick with it. As long as they are still enjoying it and so are the fans...so be it.
