There are tunes I’d love to include in a playlist, but they contain too many foul words not suitable for the bus. I’m not against foul language as I do use it myself, but there is a time and a place. Having said that, I will say I try my best to keep things clean, but every so often I come across a song with one or two words that need to be dealt with. If I find those words, I use a tool called Audacity to bleep them out. If I missed one let me know and I’ll clean it up.
