That is true. Janet Jackson and tons of other singers of the likeness use 'ass' and 'sh*t' all of the time. (Though most of the time its in the context of "get your sh*t and leave my house, i dont want yo' ass no moe"
A few is okay. After all, LP is human, and though I'm a conservative person most of the time, I can find myself swearing a billion times in a bad day. BUT- LP is famous for their no-swearing policy. If they started swearing they probably won't be allowed to perform in Malaysia (where I am) anymore. And I really do think swearing somehow decreases the quality of the music- instead of using a good word, why cdon't we fill in the missing blank with a vulgar word?
