You should listen to what everyone has to say, keep an open mind and an open ear. What people listen to on the radio, watch people's reactions towards songs, go to a music store and see what people pick up, ask the store clerk what he thinks about a certain album. everyday you can gain knowledge, but you should defintiely listen to the radio here and there to be aware of what is being pushed cus most likely that's what people really want. But i'm sure if you do that and bring originality than it'll be a smash. aint gonna sell millions but people won't deny what's good unless they are just pure haters.
