Most people swear in their songs becuz they think cool and that it will attract most listeners?

Not all people swear in their songs, and those who do don't necessarily do it to look cool or attract more listeners. Some artists use profanity in their music to express strong emotions or convey a certain message or persona. It can also be used for shock value or as a form of artistic expression. While profanity can sometimes generate attention, success in music ultimately depends on a variety of factors beyond the use of language alone.
