Writing jingles to make a living is one thing. I'm against selling one of your songs to be used in a commercial. Or selling your image or your voice. It's ok if it's a small, local business but not a big ass corporation--screw them.

I know that Tom Waits, John Fogerty and Neil Young will not allow corporations to use their songs. Waits even sued some company that hired a sound-a-like to imitate him and he won. GM wanted him to appear for like two seconds in a commercial and offered him some big money and he said no but told them to go ask Bruce Springsteen so they did and Springsteen agreed to it. However, when I was a teen, a small applicance company here in the Detroit area--Highland--used a bit of a Tom Waits song for a radio commercial and verbally thanked him at the end of the commercial for the use of the song and it's what got me interested in Tom Waits. I thought, "Man, that's good stuff!" Been a fan ever since. I know when Waits was working with Primus, they offered him money for his help and he wouldn't take it.

I definitely admire that more than someone selling his or her songs for commercials. Some might say it doesn't matter but it does.
