WHAT THE WHAT?
This is a series of Mp3 singles. Each single contains 1-3 exclusive tracks, plus the occasional remix thrown into the POA (package of awesomeness).
These releases are available for FREE. Please send them to your friends, make torrents, burn dozens of copies and hide them in public libraries.
However, if you feel guilty about getting nice stuff for free, you can support these artists by attending their shows, buying their physical records, donating money to their paypal... Links to their official websites can be found on their respective BiM artist page.
