AceShowbiz - Irish crooners Westlife regret recording so many cover songs during their pop career - insisting they have been "lazy" on many of their albums. The boyband is famous for re-recording tracks by other artists, most famously taking on Barry Manilow's "Mandy", Billy Joel's "Uptown Girl" and a cover of Phil Collins' "Against All Odds", a duet with Mariah Carey.

And despite being the only act in U.K. history to see all of their first seven singles reach the number one spot in the British charts, singer Nicky Byrne admits the band has made some "mistakes" along the way. He tells Britain's The Sun, "We've certainly made a lot of mistakes. We've recorded songs that we should never have recorded. We look back on some of them and think, 'Oh God, that was terrible.' "

"Sitting in rooms and nodding our heads and doing everything that was asked of us was what we did for years and years. But we are happy to speak now, to say, 'I think we should do this.' We've become men over the last few years."

And bandmate Shane Filan adds, "You get to a stage when you get a bit lazy. But then we'll go back into the studio and realize the last record was a bit lazy and do better on the next one."
