I can hear music in my head as if its playing from headphones but only for a short period of time and only if i know the song very well. Basically if i know all the lyrics and the melody pops into my head for any reason i can play the whole song to myself in my mind and just jam out. As far as super powers go its pretty chill ngl.

Edit: just thought id mention a slight draw back, i get a lot of awful and annoying pop songs that can get stuck in my head. If i hear a song in my head and its that clear then often it will just play on repeat over and over until i hear something else, or force myself to think of a different song which is hard to do when you have a song crystal clear playing on the radio in your head.
