I'm looking for something that builds nicely over about 2 hours. I play a lot of "Spider-man: Into the Spiderverse" right now. Or Big Gigantic.
edit: I also like to have something visually interesting to look at, since I'm just working out in my room. Lots of "visuals" on youtube. Was doing old Godzilla movies for awhile, or random Anime.
Everything from Rammstein and Metallica to soundtracks from movies/games.
