Not sure what you're even talking about with the mailman. I said (or at least thought I did) that there ARE performers in other countries who have acheived the same amount of appeal/popularity as Dylan and Lennon who would be considered equals for similar reasons, yet we have never heard about them because of the language difference not because they never developed the talent. The appeal is mostly the lyrical content and the connection to those lyrics. I don't think I said hip hop lyrics were irrelevant, they are very important, just less definitive of the entire genre than the rhythms. There is a reason that James Brown and Chic and great funk bands are sampled a thousand times more often than say Metallica or Yes (not to dig on either, just what came to mind when I thought what is the opposite of hip hop) - crazy good, funky rhythms. Just because it's created on computers doesn't mean it's computer generated, it uses lots of real life samples and takes people to program the beats, harmony, and various other assorted sounds (the computer and sound generating programs are just the instrument they choose to use). At it's core it's about the rhythms but there are acts out there that rise to the top of the genre because of the lyrical and emotional responses they evoke, for the same reasons Dylan and Lennon did. I am not saying that melody/harmony are more or less important than any other part of music, such as lyrical content or rhythmic content. They all work together and can be used in varying degrees to create great music. Therein lies the beauty of music, it can move people in many different ways using each of the various elements.
