What are all the OSTs from remade games that didn’t exist in the originals?

Question

Some examples would be Route 47 from HGSS and Zinnia’s theme from ORAS.

Comments

Ecruteak City and a bunch of Battle Frontier themes from HGSS, as well as the Soaring in the Sky theme, most of Wally’ themes and all of Zinnia’s themes from ORAS are a few I can name off the top of my head.

In RSE, Wally used the regular trainer battle theme, so ORAS's Wally theme was new.
