Wow, sir!--show some respect, the man has been dead for a decade and a half! He was a legendary guitarist/composer. Some lyrics and themes are overly provocative for the sake of defying censorship. But if that gets to you, besides the significant work with the Mothers of Invention, like We're Just in it for the Money, listen to Hot Rats, Waka/Jawaka, the Grand Wazoo, or Uncle Meat and then tell me his music stank. Some of the 80s stuff where he experimented with drum machines and synthesizers is not my bag, but for the most part it is really creative stuff that predated and influenced a lot of wonderful music that has gotten more praise than it should have.
Your opinion and mine differ, & that's ok.
