I don’t really have a favorite type of music. I like anything that’s well made. I do have a list of music types that I dislike (A lot).
Such as:
Dubstep
Most Black/Death Metal
Modern Pop
Rap/Hip Hop
Modern/Pop Country
Lazy music in general
On a positive note, plenty of the music that I like doesn’t really fall into any specific category. Two Steps From Hell for example makes music that often dips into at least a couple different types to make their music.
To put it in broad terms, I enjoy classical and electronic.
More specifically, I like to listen to a near seamless combination of the two (think Alias Conrad Coldwood) or an intense orchestra and choir (for example, Motoi Sakuraba, the composer for the Dark Souls OST)
i really like stuff in the alternative (gorillaz), pop punk (weezer [blue album], blink-182 [eots]), punk (green day [dookie-nimrod]), noise rock (wavves), grunge (nirvana), prog rock (yes, electric light orchestra), and lo-fi (joji, cloud nothings) genres
i used to really dig classical music, but i’ve sorta fallen out of listening to it recently
These days I’m mostly into instrumental and occasional classical. My picks are pretty random and often not even associated with games or movies (Jake LaVallee - Piano 1), but I prefer calming tunes, like those of Lord of the Rings. Most consistently I like celtic instrumental music (Adrian Von Ziegler).
