i soft launched http://cloudplay.fm into beta today on HN (see [1] for the discussion). it's what i use every day, and i'd love to convert you as a user :)
It looks pretty slick, but really what I'm looking for is something to manage the huge library of music files I've managed to accumulate :/ Streaming music is exciting, but not the focus I'm looking for. Thanks for the suggestion though!
