Seriously. How did I not know about this?
Since December 16, 2006 MixesDB is the database for DJ mixes, radio shows and podcasts.
Together with their dates, tracklists, file details and flyers a useful collection of artists, events, clubs, and podcasts is built:
The mixes are added by music lovers from all over the world. Our slogan: We care about correctness because most do not.
We don’t offer any downloads or secret ways to get download links.
