Okay, I am going to post in this thread since it's the first that came up in the search.
I was at work and Humankind came up on the playlist I was listening to. My coworker was enjoying it and asked me who it was, I told him "I know, I'm jamming it too", and saw it was Coldplay. We were both like, "Oh, cool." After work, I went home and looked the song up. Found out about the album "concept" for Music of The Spheres, then I decided to listen to it entirely.
I went in blind, besides Humankind, and I really enjoyed it a lot. I didn't realize until I looked up the music videos, that I have heard some of these, but never knew it was Coldplay who sang them, besides the one with the muppets, but I never payed much attention to it when it first came out.
I think Infinity Sign is one of the most uplifting songs I have heard.
I honestly think it'd be awesome if the band were to play this album in it's entirety live. Maybe, that will get me to see them live. Although, I would maybe see them if they ended up playing Coloratura live.
