I can only comment from a personal perspective, but finding places to get publicity for your music can be incredibly hard. My turning point happened when I started giving it away for free. If you license it under a Creative Commons license people can get it for free (Soundcloud has a download-feature which lets people do that). That way you can distribute your music for free against attribution, so that people have to give the artist credit when they publish content with your music in it. If not there are bunch of paid promotions that lets you get out there faster. To be quite honest, det music industry stinks, and getting out there can be rediculously hard.Hey @a100eyes! Thanks :-)
Mainly I would focus on getting out there before starting to earn money on it. The second you get "out there" people will come to you.
I'd love to stay in touch, and I'll be sure to provide you with good tips and tricks (when I get any)
All the best, man!
