Im a fan of A.Keys, Beyonce, and Rihanna I think they each offer something that no other artist is bringing, however the difference between them is that when A.Keys turns 60 she will still be able to sing all the songs on any of her albums the other two wont because of their songs content/subject matter. Beyonce is definately trying to get back to having songs with solid timeless content (4) she just needs to stay away from songs like 'videophone' and 'Run the World' though . Rihanna well...
