[SOLVED] How to add another song to this YAML file?

I have this yaml file with one song in it, but I would like to add another. The file is just this:

Code:eridblight: Borderlands 2 - Eridium Blight
Extension: audI would like to add another entry just like that, but I think I would have to make it into a list then?

This is what I tried so far, and it didnt work (i.e. the game is not loading any music now)

Code:- song1:
eridblight: Borderlands 2 - Eridium Blight
Extension: aud
- song2:
leylines: Aes Dana - Leylines
Extension: wav
