I think my favorite Coldplay song is Us Against the World. The new album was released almost at the same time when my grandma's sister died. I had a very close relationship with her and this was very painful for me, my grandma and my family at all. But this song specially just translated what I was feeling in a way that even I can't describe, and somehow gave me comfort, so although I love every single song written by the guys, Us Against the World is the most meaningful to me.
Us Against the World is one of my favorites from MX. I am so sorry for your loss, but it's almost crazy how much Coldplay can relate to you. Especially in a situation like yours. It's like...you're not alone. Thank you for sharing, dear :)
