If anime openings is to be talked about, I like a bunch:

• fantastic dreamer by Machico (used in KonoSuba)
• Tomorrow by Machico (KonoSuba S2)
• Seishun Complex (Bocchi the Rock)
• Inferno (Fire Force)
• Kaikai Kitan (Jujutsu Kaisen)
• Daddy! Daddy! Do! (Kaguya-sama: Love is War)
• Mixed Nuts (Spy x Family)
• Caste Room (Classroom of the Elite S1)
• Renai Circulation (Bakemonogatari)
• Idol (Oshi No Ko)
• Isekai Showtime (Isekai Quartet)
• Paradisus Paradoxum (Re:Zero)

I usually download the openings to the anime immediately after I watch them so that I can get my dose of anime nostalgia any time, so yeah

Resister by ASCA from SAO:Alicization is pretty good.

I’m for the Twin Star Exorcists third opening, sync. The visuals mixed with the music sends just right

I also liked Dark Seeks Light from the World’s Finest Assassin. It’s pretty experimental.
