This is sorta new to me, but I signed my band up for it last night and i'm feeling really optimistic about getting featured.
Essentially the pirate bay is allowing bands to send in submissions to be on the front page of their massively popular website free of charge. All they ask is that you have free music available or at least streaming. Heres a link to get set up with that: http://thepiratebay.se/promo
Also: Heres my band Vermin In Vinyl's new EP. It's a Punk Rock/Ska/Experimental sorta deal so check it out :) http://vermininvinyl.bandcamp.com/
As well, simply having awesome album art can be enough to bring people to listen to your music. We get more compliments almost on the album art of our EP. :P
