I don't mind explicit lyrics; I'm sure I've listened and enjoyed quite a lot of stuff that would make even the most hardened rap listener tremble with fear. I also don't mind profanity so long as they're used in the right way/mood and not for the sake of just being there, kind of like it is in
this song. By the way, profanity or not, Limp Bizkit sucks anyway. Just throwing that out there.
I don't like it when I receive something clean, though. To me "clean" means "Some people don't like swearing because they think it's bad and/or uncreative, so we blanked it out even though doing so kind of throws off the song both lyrically and musically."
There's a word I use for people like this: cussophobes.
Being a cussophobe is one of my biggest pet peeves ever. Here's something you all should know about me; I don't cuss every 2 seconds like some southern Californian, but I do like to throw around an F-bomb occasionally and it bugs the crap out of me when it bugs someone. I don't have a swear jar; I have a censorship jar (this site's rules are filling it up rather quick, I might add). Blanking out swear words in anything else is another pet peeve of mine, especially when you replace it with something that doesn't make any sense.
Really, the only time I get truly pissed at swearing is when someone uses the wrong word in the wrong context. Like for example: "I f***ing hate Linkin Park" will not incur my wrath. "I pissing hate Linkin Park" will.
Also, the lyrics don't have to have swearing to be considered explicit. It can also refer to content which some people might find offensive (and in turn, it'll likely be something I enjoy). Two examples I can give are the albums "South of Heaven" and "Seasons in the Abyss", both by the thrash metal band Slayer. I just pooled through the lyric sheets on both records; nary a swear word in sight. Why do they have PA labels? Well...just look up "Skeletons of Society", "Silent Scream" or any lyrics to most of their songs pre-Divine Intervention and you'll find out why ("Angel of Death" would be a good place to start).
Keep in mind, this is coming from someone who pays more attention to the music itself (as in, instrumentation) than the lyrics.
