Yes, it is true that Disney has made them popular.
If you’ve listened to their music you would think they deserve the popularity. Their songs are about falling love, falling out of love, diabetes [ Nick, the youngest, has diabetes] and many other teen related subjects. They make teens feel “not alone”
Most girls who happen to be in love with the Jonas Brothers like them because they are goodlooking and they have been on Disney. But to girls, like me, like them for their music, and how much of a great role models they are.
And a lot of people don’t like them, for reason I don’t understand but it is their opinion, much like it is my opinion to like them.
Hopefully this has helped.
