I have a very strong filtering despite the playlist being over 500 songs, good luck!
(If I don't like your song, I may optionally pay you M1-M50)
My offline music playlist (pastebin)
YouTube playlist that contains most of the songs, I basically download from this.
Attributes that are much more likely to get into my playlist:
anime, kawaii future bass, mainly female vocal, denpa, doujin music, EDM, wacky, celtic, energetic, jazzy
Attributes that are unlikely to get into my playlist:
background music, soundtrack, slow, simple, pure rap, calm, pure jazz, vocaloid, nightcore, trance, acapella, atmospheric, breakcore

I see you have the two portal songs, did you know there's actually a third and fourth portal song? The third is from the Portal expansion of Lego Dimensions.

The fourth is a rejected track which I don't care for but you still might want to check out.

I don't listen to a lot of Japanese music but this song Mononoke Dance by Denki Groove has the best music video you've ever seen.
Have you heard of Louis Cole?
