I never turn the music off

I can’t. There is a concert going on in my head , all the time.🤔😉

This is true. If you join a choir, practise every week, enter the music into your computer to make MIDIs or MP3s, I guarantee you you will be hearing the songs run through your head all the time. I suppose it must be the same for band members.
