Man, I listen to Rock genre and shit but man, nothing will ever surpass Eminem's badassery in profanity use. So badass I can listen to any song with a lot of cussing. When he releases shit without saying FUCK, it's out of place.
Here's a quick list of how he uses profanity words in his songs:
[RECOVERY] Cold Wind Blows: 43 profanity words
[RECOVERY] Untitled: 25 profanity words
[RELAPSE] Bagpipes From Baghdad: 16 profanity words
[RELAPSE] Underground: 30 profanity words
[RELAPSE] Insane: 33 profanity words
[SOMEBATSHITCRAZYDAY] Fack: 83 profanity words
(NOTE: The counting includes the choruses and repeated words, plus I just listened to those songs before I felt tired and jus died seepin' know y'mean?)
This also proves Recovery isn't really Mainstream, it has more cussing than Relapse and that is a surprise to me.
