Chiming in way late on this comment, but I fully feel that music in games is entirely worth your time. The music is as varied as the different types of games out there, and many soundtracks stand up on their own, and sound great on vinyl. While modern music can pull off just about anything, the stuff that is really interesting to me is the music of the 80's and 90's. The hardware was extremely limited, and artists were able to squeeze incredible sounds out of so little. I was playing Final Fantasy 15 this weekend, which lets you listen to selections from all past games, and I was reminded of how Final Fantasy 6's soundtrack simulated an opera on the Super Nintendo. I haven't played 6 in years, so this was a fun reminder of how incredible music composition was in those days. Not trying to downplay anything modern, just wanted to highlight how stricter limitation produced some very interesting works.
One channel on Youtube that I really like is 8-Bit Music Theory, who goes in depth into the music in all sorts of games. A lot of the theory of it goes way over my head, but the in depth discussions of some of my favorite music only makes me appreciate it more. On top of that, every game he's covered is worth your time as a whole. One of my favorites is a recent video about a Beach Boys re-imagining in Bioshock Infinite. Made me appreciate the work put into the cover, but also the brilliance of the original that my amateur ears would never have picked up on.
Also, if you want any recommendations on personal favorites, let me know!
