Musical motivation?

Music is a big motivator in this world. I was  wondering if the rock N roll world artists has ever done anything at all for the American Diabetes Association? Because I think if we were able to get a rock artist, whether it be a big one, like Steven Tyler or KISS, or a smaller group like POD, three doors down, to advocate this cause we could get more donations and more help in general because people listen to music, to there words and meaning. So is there anyway we could do this? Any way we could influence a artist to write a song, do a commercial or something? Does anyone on this site write music? Could you write one and publish it?
