well if it gives offence - it shouldn't

Not really up to you to say whether something you've said is offensive or not, is it?

And if your definition of 'folk' is down to its appeal to ordinary people -

music they will dance to. music, they will sing to. music that entertains and amuses them. folk music. music for folks.

- does this make Justin Bieber a folk artist? If not, why not?
