Rumors are rife that Bono is having trouble writing songs for the new U2 album.
Sources revealed that the delay is not due to disharmony in the band but because the 53-year-old Irish singer-songwriter still hasn't found what he's looking for, the New York Daily News reported.
Sources added that as Bono is struggling to pen new lyrics, the band has delayed their plans of releasing a new album and their much awaited world tour.
