The Pet Shop Boys have become the lastest band to hit out at ITV talent show, X Factor.

The group claimed that “X Factor music” is “ultimately turgid” and real pop songs would stand the test of time.

“Good pop music doesn’t really date. Look at Abba. Unfortunately they’ve become a kind of a cliché because of Mamma Mia! but ‘Knowing Me, Knowing You’ is an amazing record,” Neil Tennant told The Sun.

“The backing vocals are outstanding and the video is harrowing because their marriages are breaking up.”
