Well, deficiency, be gone!
I think the song is a little strange. After all, by virtue of being in a band, they are already the cool kids. But it's a fun song - a bit of an 80's throwback, in my opinion. It's fun, and I like that an unknown little band of kids suddenly had a top 20 hit.
Little known fact: that was actually the 2nd video for this song. Turns out the song was almost two years old before it was a big hit.... and I like the performing-in-the-living-room aspect of this one a little better......
But, they're still a bunch of cool kids.
