There's a
tremendous variety of primarily instrumental music out there. If you've found one, don't forget to look for more, heh. It's always nice to listen to new music that appeals to you, and it's definitely easy to not realize just what or how much fits in that category if you don't have much exposure. Oodles and oodles of free stuff online these days, too, if the cost is an issue... and that's
not counting youtube et al that has close to everything even if it's not exactly licit.
And tack, yer a freak
Or haven't found the right sound, yet.
More seriously, there's plenty of reason to enjoy music that doesn't involve any particular emotive reaponse. Probably half the stuff I listen to is mainly due to the skill or complexity involved with it -- it's pleasing/engaging/etc. to hear someone exercise a skill, sometimes even if the sound itself isn't entirely in tune with my tastes. Good chunk of the rest is because how well they lend themselves to accompanyment, not listening for the sound itself so much as the opportunity to work the voice (or whistling). Is particularly a thing if you have any instrument training you have reason to keep up on. Though not liking the quiet is a reason, too, sure... probably one I'd personally recommend against cultivating, since being able to be okay with just your thoughts and all that is pretty import, imo, but a reason nonetheless.
