song writers

[sleaver]

who is the most successful music writer in terms of most published sheet music sold including clasical and pop and rock music

[Mortartube]

I can't say for sure but I am guessing that Irving Berlin and Burt Bacharach and Hal David up up at the top end of the list.

Carol King, Lieber & Stoller, Lorenz and Hart, Rodgers & Hammerstein are probably all contenders too.

Define successful...

In terms of records sales, The Bee Gees also have to be up there, believe it or not.
