If you’re trying to steer away from the corporate catergory, catchy rock music is always sellable. I’m going to make more myself after my track “Energizing Rock” sold 7 times in the first week (one of which was an upgraded license).
That being said, I try to be very versatile in my genres. If you check my portfolio, you’ll see I have some cinematic tracks, some pop/rock tracks, corporate tracks, electronic tracks, and even a few sound effects. I do this because in the future, when I make more of a name for myself, I want my clients to know I can make any kind of music they need, so they keep coming back to me.
Hope this helps!
