If we're talking about music in general through the show rather than just the intro - The Korean High Fantasy series Arthdal Chronicles. Some stunning, music, throughout, the show. It was also kinda like watching a JRPG (even if Korean).

Also the Alice in borderland score is pretty powerful. Some intros that are solid also:

Babylon Berlin intro captures the art, the deco, the decadence and the violence of what the viewer knows is going to come of that time period.

Black Sails just perfect

Raised by Wolves I was hit and miss on this in many ways, but this intro is great - albeit I think slightly misleading as to its overall tone.

Pennyworth I thought S1 was a bit silly, but what an intro.

Happiness This is just fun, and fits the show brilliantly
