Kuma, what you describe fits Synesthesia.
I love music myself. It just takes me away.. it's almost meditational... But for some reasons not quite.
I have favourite songs, and more get added to my list as time goes by, and the one's i've loved, i'll most likely always love (unless they represent something that later I reject.. ideas, beliefs and the like that is) But for the most part I have a short list of songs at any time (sometimes only one) that I just die to hear.
That's kinda why I can't listen to music much. If i do, i'm not here anymore.. I'm gone, totally into the song, if it's the right song, if on repeat, hours can be gone. if not, the awakening when it's over .. just 3 to 5 minutes.. and it's like running into a brick wall.. it's like Where did that come from!?!?! (as in the end of the song.. the silence)
It's too hard to come back sometimes... But sometimes I do need to go there, where no one else is there, even if the room is full of people.
It's a different kind of zoning out with me. Normally I zone out to think... to ponder, to figure out what the universe is. Not with music. I just become the music, i enter the music, and I am free of everything but the music. It could become an addiction to me too. Actually it has been, and I've recovered. It made nothing matter. But everything matters, and denying that is denying life. Music is a dangerous tool in the wrong hands. It is a powerful tool in the right hands. Be careful what you listen to.
Oxytocin, oxytocin, oxytocin..... dang that word ain't the most musical... but it is what the body releases.... And outside of listening to music, I don't think my body knows how to release it.... So when it does... it's powerful.
