Do you think cuse words make songs better or worse?
If they are being included for “shock value” , or to denigrate other people, then they definitely make the song worse, but if they are there to convey a concept that just cannot be verbalized any other way, such as “as f**ked up as it all may seem” from “It’s Been Awhile” by Staind, which is very integral to the whole tone and point of the song, then it’s ok.
