I wouldn't say any genre is the "worst" however some are just so simple and cater to simple minded people Like a lot of modern country is the same exact 3 chords and is always about booze or trucks ect, and isn't even country. Just pop with a southern accent.. Modern rap has no effort put into it whatsoever Most "Metal"core/screamo bands play the exact same 3 chords and it's listeners are probably the most tone deaf. Every song has the same generic breakdown. i don't understand why it's so popular Emo pop is probably the most annoying IMO. The vocals are all the same. distorted bass is way overused
