Who do you think the most prolific musicians are? The music business has changed so much over the past couple of decades. In the '60s and '70s, it wasn't uncommon for artists to put out a new album or even two new albums every year. Granted, most albums are longer now than they were then, but I think artists were able to put out more work then because labels didn't have such strict schedules when it came to marketing each record. etc. (Hence the reason Prince wanted out of his Warner Brothers contract several years ago)
Here are some artists I think are still very prolific:
Macca - Not at the same pace he was in the '70s, but with all of his side projects he stays very busy.
Van Morrison - He still seems to release a new album every year
Elvis Costello - Ditto
Neil Young
Prince
Elton John (Although he's slowed down a bit recently)
Beck (Unfortunately I think Geffen has slowed him down a bit because he used to release a lot more records on independent labels in addition to his "mainstream" records on Geffen)
Granted, being prolific doesn't always mean the quality is going to match, but I'm still amazed at the work ethic many of the above artists have. I don't see many younger bands working that hard.
