Know your audience.
Don't ever lose sight of the music, but do read your SoundCloud comments and check your social media accounts to see what your fans respond most actively to. See which songs get the most plays and try to gauge why. See where people are playing your music and if you start touring, target those towns and cities. Try to figure out who you want to reach, and how to best reach them. At the end of the day, the more you know, the better you can prepare for success.
Speaking on the genius Rae Sremmurd campaign that helped drive "Black Beatles" to the No. 1 song in the country, Interscope's Gunner Safron explained, "The general idea is taking the approach of new songs, new artists, music in general, and marketing it almost as if I was a music supervisor. Really just trying to pinpoint an audience and figuring out what’s going to drive the music to that audience. It’s different for every artist, and you have to tailor that approach to each one."
