Those artists you mentioned are 'legends' to some, king of rock and roll, queen of country, old timer still going strong and a diva (that I like too) but Susan Boyle appeals to the ordinary person on the street, well those that like her and as pointed out already, she's inoffensive - she's easy to listen to and seems genuinely a nice person, I like her because she didn't get there easy or through life easy, it's a great break for her
