Coldplay is a very talented group. I enjoy their music because of its deeper messages: many of Coldplay's songs are meant to teach a lesson or inspire. Coldplay constantly changes its musical styles (especially with its new song, Every Teardrop Is A Waterfall), yet everytime I get the same feelings from it; at first awe, then understanding as I attempt to decipher Coldplay's deeper meaning in the song.
It is nearly impossible for me to choose my favorite; I enjoy all of their slower, more beautiful songs such as The Scientist, Fix You, and Lovers in Japan. However, I also love their upbeat songs like Rainy Day and Every Teardrop Is A Waterfall.
I've only ever really liked a few of their songs, but I might not have tried that hard to find any others... However, I will not deny that the singer has a nice voice.
