i've found a few here that i really like. and they allow uploading of your own stuff if you want. good way to host mixes out there with a streaming and dl link. it's free.
i put my underworld mix and progressive classics mix up there.
also, some good stuff on my updated website; live set from Bonkers! and an ambient set from the WET Gallery in Seattle. There were a lot of sculptures of bugs.
