I wrote most of the code for Audiomack. Free music hosting for artists. Predominantly hip-hop/rap because my cofounders have had other ventures aimed at that genre over the past decade or so, but audiomack accepts everyone. We'd particularly like to make inroads into electronic & dance music.

Started it in our spare time, launched Feb '12 and I went full-time in May '13.

edit: interview with my cofounders for anyone interested in the ideas behind audiomack http://www.youtube.com/watch?v=6S1Vb0PE7w4
