Hey,
That sounds awesome, I am curious, how do you work with the providers (google, soundcloud and co ..) so that they can make some revenue ? (because you know these guys are just not streaming music for free ...
Also I tried the web-app with a good album (Pixies - Doolittle)
http://toma.hk/album/Pixies/Doolittle
but all the songs in that albums are actually covers or remixes and none are the original Pixies version ... (probably what's happening when you look for "pixies debaser" in youtube or soundcloud.
Anyway, the interface is super polished and cool, and I really like the idea of "having everything in one place" + jabber integration, there is really some major things to do with this, and there you are..
