Promoting your music on social media is a smart move. From personal experience, engaging content and consistent posting have helped me get noticed. I'd recommend TikTok, Facebook, and Instagram. Spam TikTok and Instagram Reels with your videos, 1 from 10 might go viral.
If you want to use paid ads there, I'd recommend using adspy. I used it to see what campaigns my competitors run on social media. It helped me to find out which tactics drive traffic for them, and I implemented them in my strategies to get traffic.
