In listening to the new, kinda boring Hives album, it makes me think they should reinvent themselves as a "punk rock" kids band, like a hardcore version of the Wiggles. They've pretty much taken the indie rock thing as far as they're going to take it, and this could extend their career another 5-10 years.
They've got the wacky synchronized outfits happening, and their sound these days is way watered down while still being somewhat catchy. I'm pretty smart so they should take my advice.
