How many posts are there on this board asking that exact same question?
Genuine question, I think is the third time I'm about to type: "Rappers, singers, songwriters write about what they can sell to their audiences." Burt Bacharach wouldn't write songs full of urban slang about his many problems, a la Jay-Z, and the Wu-Tang Clan wouldn't sing about falling in love (I'm willing to bet…).
I don't really see how naming a song "Wu World Order" makes for much of a discussion, to be honest.
