Be prepared to lose a lot of money and/or not make much money at all for a while. In fact, use the music as promotional material and work to get your acts bigger gigs to play live.
Know marketing…and think marketing. Don’t just sit there thinking like a DJ or music nut. Don’t get mad if you see “crap” selling like hotcakes while your “better” stuff isn’t.
Be in it for the right reasons, and treat it like a business. If you guys just want to make the music you love, but think not many will be into it, then you might want to go smaller and just be a group and push yourselves with freebies all over the social media networks.
Again, I notice the bigger money is in the live gigs…way more than selling tracks.
