I've thought for some time to post cool artists or groups I find on SoundCloud and I'm going to start right now with a great group simply called Edits.
It's basically a place to upload your own edits for others to listen and, if you choose, make available for download. Edits is big enough now that you could find literally dozens, if not hundreds, of quality edits to download in 320kbs quality.
The theme seems to be slanted mostly towards edits of old disco, funk etc but there are others there too. If you're familiar with reknown edit-makers like Leftside Wobble or Hawk then they're two of the moderators of the group so you know it's going to be mostly quality stuff.
