Answer:
Well, for relaxing music, I'm sort of into Indie myself. So here's my relaxing music playlist:
Lisa Mitchell - pirouette
Sia - soon we'll be found
Angus and Julia Stone - big jet plane.
Lisa Mitchell - valium
Sarah Blasko - bird on a wire
Angus and Julia Stone - paper aeroplane
Coldplay - the scientist
Sarah Blasko - we won't run
Not too many songs there, but on repeat they're really relaxing. Enjoy!
