I personally find Van Halen to be a bit overrated. But they do have a few songs I really enjoy and that's one of them.

All these folks pretending it's not Jump, give it up guys! Every band in the World wishes they wrote that song, pop perfection.

Right Now is my favorite of their songs.

My favorite LP is Fair Warning, but I think my favorite is D.O.A off of II. Four people, all playing like they think they're King Shit. Awesome.
