Now, for more than 185 broadcasts long, netwaves is reporting from the musical underbelly of the internet with interviews, reviews and DJ-sets, every week on Belgian's oldest free local radiostation, Radio Scorpio. You've been able to download every episode as a podcast, but since a while you can download all the music from every episode as a compilation.
All this music is released under a Creative Commons license (except where noted otherwise). This means you can download, copy and spread this music provided that you mention the artist name and don't ask for money, hence "Not for sale!"
