Nice thread idea, Angelo. The greatest pop/rock music composers, at least to my mind are - 1) Lennon and McCartney, perhaps THE greatest songwriting duo ever. 2) Bob Dylan, say what you want about his vocals, he was/is a brilliant songwriter. 3) Paul Simon, just a fantastic songwriter. I love many songs he wrote for himself and Art Garfunkel, and also many songs he wrote after going solo. 4) Willie Dixon, he's my favorite blues music songwriter. He wrote many classics for both Muddy Waters AND Howlin' Wolf. 5) Warren Zevon, a brilliantly quirky and very descriptive songwriter. If you know his work only for his "Werewolves of London", please check out virtually any of his other work. You'll be glad you did. The songwriting team of Elton John and Bernie Taupin just misses my top 5.
