Funny thing is - quite a few songs have been mixed in 360RA already. I seem to remember them not sounding very good... But I'm pretty sure they at least had discrete elements?
The tracks were -
All My Life
Best Of You
Everlong
The Pretender
My Hero
Learn To Fly
Times Like These
This Is A Call
I don't think they ever appeared on Apple Music in Atmos before this new GH release? I'll need to check them out again. They do still seem to be on Tidal in 360RA...
