I disagree with the following:
- 48-Master P 
 47-Goo Goo Dolls
 46-The Spin Doctors
 37-The Doors
 35-Paul Oakenfold
 34-Live
 25-Jamiroquai
 8-Vanilla Ice
 7-Asia
 5-Starship
 4-Kenny G.
Those bands/groups should not be on this list where they are, if at all. I disagree with the list in general, but IMO the bands above stand out as ones I would not put on it. 
Music is such an individual preference, that these lists almost always are a joke unless they are based on data, like sales, etc.
