I beg to differ on their quality of artists. As for their quality of files I don't know, I just browsed the site when the Nomad deal was around to see if there was anything I would download, then decided to wait for payday and missed out on the Nomad. If you are looking for obscure acts, they seem to have a good amount. Of course they aren't going to have Ricky Martin's and what not, because obviously Ricky doesn't need any help selling albums. The sheep buy that crap up.
Blackalicious, one of the most intelligent groups in hip hop today have their out of print debut EP, Melodica, there. As well as their newest LP Nia, and another EP A2G. If you enjoy hip hop, and are not close minded to exploring new artists please check them out. You will not be disappointed. Also look for Anticon, another highly intelligent group of hip hop artists.
A little off topic, but oh well.
