I am currently fiddling around with Blip.FM. Since I never bothered to follow anyone on Twitter, this new social music site passed me by. After playing around with it a bit, I must say that it is a much easier way to find music than on the deceased Muxtape.
I signed up this afternoon and I am now collecting a track list that is deemed to become very eclectic.
Make sure to drop by at StellaVista´s Outer Base. Slip into something comfy and pour yourself a drink.
The server seems to be quite slow and overpowered at times. You also have to wonder about the legal aspect of the whole thing. As soon as you upload anything you are practically committing a crime. I am expecting Blip.fm to be shut down in Germany pretty soon (now, that I have found it...)
