I had been using btunes, seems to work pretty good. Just got on the Skytunes kick since beta was released last week. It's an Adobe-Air app, streams music on my Mac Mini to my Evo via 3G. Good sound quality, unlike Pandora. It's got some small bugs, but it's still in beta. I haven't added everything on my Mac to the program to stream. I tried to do it all at once, but I think it was an overload for the Mac app.
