Clocks made me want to find out more about them. I had heard Yellow, but didn't know it was Coldplay. Fell in love with God Put a Smile...Played the heck out of Parachutes and Rush/Blood to the Head over and over everyday for three years. Just couldn't get enough of their music, I discovered different aspects of each song so I never got tired of them.
Fell in love all over again when I saw them in concert last month. Just a totally awesome band.
