U2 cite how the want bands to come through the ranks in the modern era and like to give a chance to decent if not very established acts. I would think that this goes against a lot of what they stand for as a band.
Simon Cowell's poptart-producing machine (aka a 'toaster') has encouraged a musical world of very good singing voices but little else in musical talent.
When you think of some of the best song writing musicians it has to be said a lot of them don't have particularly great singing voices - Win Butler, Francis Black, Bob Dylan, James Murphy, Steve Maulkmus are some that come to mind.
I remember doing a study on the effects of modern age media promoting beauty on what people determined as beauty in other people and people are definitely affected by this idea of 10/10. Similarly I think by focusing a lot on people's singing voice a lot of other things are missed over.
Well, that's just the rambling thoughts of a guy who's only a 9/10 in looks
