You need to understand that ESO add-ons are very limited, unlike Skyrim mods.

If you are not convinced by the conclusions reached by those more familiar with add-ons than you, you are free to use your own time to investigate whether add-ons can do that.
And perhaps you will notice that it is much easier to listen to your favorite music at any time by a portable music player or other external application rather than an add-on.


And well, a positive approach would be to gather supporters to petition ZOS to implement orchestrion feature.

If the orchestrion is introduced to ESO, it may be possible to change the music with an add-on.
Once you've worked hard and persistent enough on that plea and moved the ZOS developer's heart and ZOS finally implements orchestrion features other than music box furniture, I might consider doing something with my jukebox add-on. That is a long way off. Good luck.
