I suppose it depends what you mean by bigger. For social impact, greatness of songs and longevity it’s a no brainer. Please don’t tell me in forty years time folk will be learning to sing and from The Mariah Carey Songbook. Someone earlier mentioned doing ‘Like A Virgin’ in a covers band, which I think is cool. But how many bands are covering (or even listening to) Madonna and Carey compared to Elvis and The Beatles? another no brainer. I could not even entertain the thought of Mariah Carey being in a list of all time greats (all time great screecher and self important drama queen maybe) – Madonna on the other hand I could make a case for. So to paraphrase a UK sketch show, if Mariah Carey came knocking on my door and singing “I can’t live if living is without you” I would say “Mariah! No!!” “You may well be the best selling, highest pitched diva around but go and sing in the next street” smile
