If by "rock'n'roll" you mean:
4 chords on repeat for a whole album, backed by terrible prepubensent vocals, a shockingly basic drummer and songs about saving your virginity until your at an age where your junk won't even wanna perform anymore, because it's too embarressed and ashamed to see the light of day, and it just doesn't really wanna get hard over screaming 9 yr old girls who have "tickles in their 'ginis".
If by "rock'n'roll" you mean:
Keeping it so clean, that your fans will remain niave until they are probably put into a social situation where they panic and say "Jonas Brothers didn't teach me about this!"
IF by "rock'n'roll" you mean:
Music that not only insults our intelligence, but also insults young children by marketing Jonas Brothers products in such a sexual manner, yet they apparently preach "no sex before marriage".
IF BY "ROCK'N'ROLL" you mean:
Three fagets who can't play live, who can't sing live, who can't perform live, whose audience wouldn't know a decent song if it came up to them and pricked them in their ears.
And if by "rock'n'roll" you mean:
Three boys who's musical talent and heaviness could be worse then Hanson.
If by "rock'n'roll" you mean all of this...
...then maybe you don't know what "rock'n'roll" is.
