Most jazz acts never had any hits and they generally don't release singles. They don't get Top 40 airplay. Wynton Marsalis has been around for a long time and doesn't have any hits. Bobby McFerrin has been performing for over 20 years and only has one radio hit. Acts like Sonic Youth, Iggy Pop, The Grateful Dead, Phish, or Jimmy Buffett don't depend on radio play. They have more of a word of mouth following. Look at Genesis. When Peter Gabriel was the lead singer, they were an underground prog rock band with weird lyrics and Peter's crazy costumes. Genesis first album was released in 1969, but they didn't have a hit song until 1978, which was 3 or 4 years after Peter left. They basically changed their music to a more pop radio friendly sound, and that's when they started becoming popular. Having a lot of hit songs or selling big are mainly criteria for pop acts, not for other genres. Whenever somebody makes a list with the biggest selling albums or acts a bluegrass, classical, blues, or jazz act is never on them.
