Pop Quiz

I may be muscling in on Mustang Bobby's act here, but today seems like a good day for a completely irrelevant question. Sometime relevance is overrated. So, here goes:

Who were the great pop music composers of the twentieth century--the ones who will last well into the next century, or should?

The only rules are these: we're talking pop music, not serious music; we're talking writers, not performers or producers; and we're talking about a body of work, not just one or two great songs. Since most of our experience is likely to be Anglo and rock/jazz/show centric, extra points will be awarded for other culture, other genres, and forgotten masters. I'll spot you, what I think are, ten obvious ones.

Cole Porter
Duke Ellington
Irving Berlin
Lennon and McCartney
Bacharach and David
Richard Rogers
Holland-Dozier-Holland
Stevie Wonder
Anonio Carlos Jobim
Fats Waller

Who else belongs on the list?
