I Would Say I Have Heard It Once and Only On Radio.
My favorite would have to be Frank Zappa. I like his music, lyrics and message he try to pass through his genius. He is not only rock musician but as well composer, poet, writer and representer for many in music industry. It is sad that you have no chance to listen some of his music. Instead of it i can hear or the "try to be music" hip pop or other rubbish. Well we are surrounded by cheese I may have to say
