All i know is that coldplay's new album Viva la Vida is a top seller, so a lot of people like them.
Beyond that, this band's listeners seem to have a special loyalty and love for their music as a whole. I have a lot of friends who are definite cold play fans. I am not a big concert man so i don't know much about a coldplay concert in comparison to a U2 concert(which i hear is incredible).
This is a sample of coldplay's new song
And i know that a lot of U2 fans would get mad at me for putting Coldplay and U2 on the same level, but i would expect nothing less from their loyalties!
The music, the following, the loyalty, and many other similarities make is seem like it is inevitable.
Please correct me or give me your opinion if i am wrong.
