For me:

Babylon Berlin intro captures the art, the deco, the decadence and the fear 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.

Warrior

Happiness This is just fun, and fits the show brilliantly

See also isn't bad

Song of the Bandits The song on the YT video isn't great here imo, but they actually mix it up in the show proper and use different songs. And some really fit the theme.

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).
