12). Army of One by Coldplay
I don’t know about any other artists who compose as soulful songs as Coldplay and Army of One is one such example which I included in this list of songs about loneliness. This indie song was released in 2015 in the album A Head Full of Dreams.
The song shares the feeling of a guy who is feeling very lonely after a heartbreak. He has been to everywhere but not feeling content anywhere. But still, his hopes to survive as the single man army tells that he is positive about his life.
