online mixed tapes

This morning I just discovered the website, 8tracks.  According to the description on the site, 8tracks allows you to "Listen for free to the best internet radio, crafted by people who know and love music. Or, legally share your own online mixtape, a streaming playlist with eight or more tracks."  The site is full of free playlists.  I am currently enjoying Badasssss!, a mix of 15 rare blaxploitation tracks from the funk/soul era..
