I actually really like them. And Miley! It's fun to listen to something that doesn't have "serious", "deep", or "dark" lyrics. Just because they're geared towards children doesn't mean that they lack talent. I'll admit, they don't sing spectacularly, but their songs are catchy and insanely fun to drive to. No, none of them are attractive - they're much too young. Besides, would you let your ten-year-old listen to Slipknot? Ludacris? Brokencyde? I wouldn't.
That said, I voted 'no'. To put it simply, they are not Hall of Fame material. It doesn't matter how catchy their songs are, they aren't cut out to be in the HoF.
Honestly though, all the talk about killing them is sort of immature. I'm not singling anyone out, I just noticed it twice in the thread.
