Keane suffered "constant abuse" in their earlier career.
The 'Everybody's Changing' band are returning with fourth album, 'Strangeland', and are more confident in the own abilities, having overcome prejudice in their early career from people who seemingly disliked them because of their privileged roots.
Singer Tom Chaplin said: "As a band I think we've suffered a lot of judgment."
Drummer Richard Hughes added: "It was constant abuse for a while. But our fans have stuck with us and we're still here making the best music. And it's OK to like Keane now."
Chaplin's confidence was affected by the criticism, and he turned to drink and cocaine.
He has since recovered, and with 'Strangeland' feels he's finally found full belief in his own abilities.
He added to The Sun newspaper: "It's probably not until this record that I have ever felt super-confident about being Keane's frontman. I've been a dribbling wreck, full of insecurities."
Songwriter Tim Rice Oxley - who completes the band with bass player Jesse Quinn - said he hoped the record will "connect" with fans better than their last albums.
He said: "One thing I regret about 'Perfect Symmetry' and 'Night Train' is that we weren't connecting, getting the emotions and stories across. I wanted those stories told clearly on this record."
'Strangeland' is released on May 7, and Keane have today been added to the line up of T in the Park festival, playing the Main Stage of the festival, which takes place in Kinross, Scotland, from July 6 to 8.
