This resource pack, as the name suggests, backports new music to older versions of Minecraft.

The pack is split into 3 versions:

1. Pre-1.13: Adds all new songs
2. 1.13-1.15: Does not add Update Aquatic songs
3. 1.16+: Does not add The Nether Update songs

Technically all pack versions work on all Minecraft versions, so you can even install pre-1.13 on 1.21, just keep in mind that all tracks will play everywhere instead of being biome specific.
