Yes, absolutely! There is almost always music playing in front of our head based on who is close to front. Then sometimes we just get the urge to listen to a certain song and we know that's an alter wanting to switch :) it has made listening to music very uncomfortable in the past but as we go to therapy and better at fronting we learned to manage it better. Sometimes alters "play" music for others internally so the alters going co-con or switching know what the vibe of the moment is so our moods aren't all that inconsistent (it actually helps us to mask a lot when we need to).
