Too many to name, and I'm just heading off, so I'm sure I'll miss a ton. I also don't have my full list, since I still haven't fully recovered from a certain site going down...thankfully I did back it up, just haven't sorted and imported yet.

Starting off, Chivalry of a Failed Knight...both the OP and the ED, as well as the full version of the ED.

Takt Op. Destiny OP. The Full version is nice too.

Akashic Records of Bastard Magic Instructor OP.

And, a meme, but deservedly so: Bling Bang Bang Born (Mashle S2 OP.)

Shield Hero S1 OP.

Almost anything by Myth & Roid, Overly Cautious Hero OP for example.

Yuru Camp S1 OP. You really can't beat the chill here. I dare you not to smile.

Oh, how could I forget? Fire Force S1 OP, and Fire Force S1 ED.

Can't help myself, here's a few more:

Skeleton Knight in Another World OP.

Dead Mount Death Play S1 OP, and Dead Mount Death Play S1 ED.

Food Wars S1 ED. Another try not to smile one, especially at the shift at 52 seconds.

EDIT: Mononogatari Malevolent Spirits S2 OP.

And many more. Might list some more when I get back if I feel in the mood.
