This isn’t very long, nor does it have individual pictures (though each song has a link) but I did want to get it out there. Songs that are covers or remixes of previous OP/ED songs that had that status for more than 2 episodes are banned. So no Kirameki Slow or Unravel Acoustic. Just insert songs for this one. I also don’t even have to remotely like the show they are from to like the song, and vice versa. One per series. I’ve heard literally tens of thousands of anime background tracks, and these are the top 20. Me liking the show helps to an extent, but the music making the scene better is what really matters, along with being fun to listen to on it’s own. No descriptions, but runner ups are listed if there are any.
Runner Up: Dragon Force
Runner-Up: The entire rest of the soundtrack
Runner-Up: The Master
Runner-Up: The Whole fucking Soundtrack
Runner-Up: Before my Body is Dry
Runner-Up: FLCL has by far my favorite anime soundtrack. Little Busters, I guess? Or Bran-New Love Song.
