Susan Boyle has been singing for years dumbf**k, she isn't new by any means.
that may be true but out of everyone to compare, you say eminem??
he's been making music for 10+ years, but not just music, hit records that we all know he was deeply involved with including production
considering everything that goes into a track: the beat, the lyrics, the concept, the putting of it all together, the vocal layout
what makes you think that susan boyle does all of that better?
the fact is that susan boyle needs much more people to make a track than eminem does
