Martin still not convinced of Coldplay success

Rocker Chris Martin is amazed his band Coldplay have achieved international success - because he is convinced they've never produced anything "that good".

The 'Speed of Sound' hitmakers have released three albums to date - 'Parachutes' in 2000, 'A Rush of Blood to the Head' in 2002, and their last LP 'X&Y', which went to number one in countries including the UK, US, Australia, France and Norway in 2005.
