Eric, don't be naive. If Madonna records a song and it's a single, it is guaranteed airplay, simply because it's Madonna. Sorry, but that is the reality. I'm not a fan of hers, I don't own any of her records and probably will never work with her. However, she is the biggest star of her type, she owns her own label, her stuff is going to go on the air and into movies and TV shows. It's her label. All those resources are at her beck and call.
Saying that she doesn't have a built in audience is like saying that U2 doesn't have a built in audience. That is silly. They do. She does. Radio stations will play her. That is almost as certain as knowing the sun will rise tomorrow. If she records and releases one of your songs as a single, you are going to make six figures, guaranteed, even if it's a flop by her standards.
Madonna not withstanding, you're hijacking the thread again, Eric. Relax, dude. You're in good hands with ASCAP.
