I tried Morpheus but the availability of titles was pretty meager at that time, and their software had some spyware built in. I suspect the others do as well. What I've been doing is going to the Wherehouse (there's a few in my area that haven't closed down) and buying used CDs willy-nilly. I've picked up a lot of the titles that were recommended here, and many others that "looked" good (judging a book by its cover), whether I'd heard of them or not. Burn them all and take back the ones you don't love.
I discovered a huge number of jazz artists that are just awesome - Billy Ross, Arturo Sandoval, Ottmar Liebert, etc... In fact it seems like 95% of the Cds in the used jazz section are keepers. Blues, too. And reggae.
