Ok this is not spam! But I'm a novice DJ/EDM producer and wanted to know if anyone here knew of any free advertising tactics.

Because I don't want to get marked for spam I'm not putting the links to my music on here, but they are in my sig.

~thanks

Make a blog (on WordPress for example), make meaningful posts and then network with other bloggers. Like their posts, comment on their posts, subscribe to their blogs. Most of the time they'll check you out in return, and that's a potential listener I suppose. Networking is the best free advertising.
