If you consider that Ledbelly may have never written an original tune that we ever heard, but was a heck of a good 12 string player, it's interesting.

If you buy enough recordings you can have a complete Ledbelly collection in fairly short time. That's everything of his ever recorded.

Same thing happens with Django Reinhart music. There are a limited supply of recordings, which are re-packaged and re-mixed, over and over.

Haven't heard Moby so I will defer any judgement or opinion.
