...Anime, TV, movies, games.

"Music" in its modern mass-consumed form is pretty trash, but when the music actually matters is ironically when it is not the main point. The "main point" music makes for bland, samey, easily-consumable blah that carefully avoids inspiring any emotions in you to make for simple listening, so you don't STOP listening.

But music from other media requires itself to invoke emotion in you. And, of course, brings back memories of the media it is from. But if I'm listening to music, I'd rather feel angry, pumped, fearful, or even depressed, than feel nothing at all.
