In year 2003 I did this often.
As a spirit, you don't normally have ears, so the easiest way to hear and feel music is through the thoughts of Humans or animals while they listen to it.
Just listening will have this effect a little, but to make it very powerful you would try to broadcast it to spirits, astral, high levels of consciousness, and whatever or whoever else may be listening to the thoughts you're trying to broadcast. You wouldn't try to prevent anyone from hearing your thoughts. Instead, its a feeling of being very open about whatever you're thinking, not caring if the whole world experiences every little thought in your mind at the time, and its lots of fun.
The spirits listening to your thoughts as a musical broadcast, are not only observers. They sometimes flow their thoughts with yours, and the experience is amplified for all involved that way.
I didn't know this at the time, but I think that was the main source of my metaphysical abilities. It started as just something fun to try, but as more and more spirits came to listen to my experience of hearing the various music, I started getting gifts of metaphysical energy, or you may call it a trade but I was broadcasting those thoughts because I wanted to regardless of if I got anything for it or not.
When I had a huge audience of spirits, who came at various times depending what music I was listening to and broadcasting my thoughts of, and I continued becoming more connected to that world, and receiving gifts and/or trades of metaphysical energy for my musical thoughts I broadcast, I became so powerful I was able to do the following mind over matter in this video recorded in 2003:

The metaphysical energy and other abilities amplified the musical experience and broadcasts, attracted more spirits, and it snowballed from there. What happened near the end of those 5 months I don't know how to say in words, but I would never again think of reality as most people understand it.
Because of some medical problems later I lost the ability but its now coming back, and I only recently remembered it.
Maybe it was because at the end of those 5 months I had only 1 fear, not being tortured or covered in spiders or anything most people can imagine... my only fear at that time was losing the state of mind I had learned and not being able to figure it out again. I wanted to know if I could figure it out again if I had to start over. Maybe that was what caused the medical problems that I am now recovered from and getting back my metaphysical abilities. I am again a metaphysical musician and building amazing things. I'm now more scared of torture and being covered in spiders than I was back then, but at least now I'm not afraid that I couldn't figure it out again. I'm not at all scared of death or even the pain of dieing since I've been through much worse than that and am back doing what I love, and will continue that wherever I happen to be. I've learned all the major things I need to learn from Earth, and I'm here now mostly to give the Human species some tools in case some of you want to explore various parts of reality.
For years I've been building free open source software tools to network our minds together through the Internet, through the psychology of feedback loops of realtime interactive music controlled by artificial intelligence in reaction to mouse movements, to access each person's subconscious psychology and flow that with the patterns of other peoples' thoughts through the Internet using intelligent statistical software. Try the early version of Audivolv 0.1.7 here http://sourceforge.net/projects/audivolv
and later the whole system will be Human AI Net http://sourceforge.net/projects/humanainet
I have many reasons for creating this global network of our subconscious thoughts flowing together. Now I remember what started me on this path. I'm a metaphysical musician in many ways, even when only remixing thoughts of music I'm listening to. I want to become more, and to give others the tools to do the same, so I have some artificial intelligence music psychology software to continue building.
Nonexistence is isomorphic to the set of all self-consistent possibilities. That's the math way to say the universe is simultaneously everything and nothing, infinitely balanced, timeless unity, zero. But that is only 1 side of it, and the other side is all possibilities of existence individually. We oscillate between them in various patterns, and it can be a form of music if you use it that way.
