IMO Coldplay, Elton John and U2 all write their own music, Sugababes, Blue, Robbie Williams, Busted and anyone from X Factor don't and therefore they don't know music till they can write a good number. I would say Dosser Jacket is a better artist than the later of those. Definately a similarity between Dosser and Bono.
But if they write shite music ?? But....of course...all subjective and who am I to say Elton's shite but as it's a thread asking for opinion then that's mine. I'd rather listen to a wet fart tbh
