Via the CC blog - where netlabelism/netwaves was blogged today :-) - i discovered the existence of ccNeLas.
NeLas started to blog with the same reasons as me: "Since I've been listening to excellent songs published under Creative Commons licenses, I decided to create this music blog and promote these artists. So, ccNeLaS is my personal selection of songs, organized by genres!"
Earlier today, I encountered another interesting project: CCHits, a social website with an interactive chart of Creative Commons music. I tried to add a song (Tape Tum), but i found it a kind of taking too much time. Just try it yourself (membership!) and leave a comment.
