I vote for Nickelback because of their immensely and obviously formulaic songwriting, but Foo Fighters are close behind despite having produced a few good songs. What someone said about U2 earlier, though, I totally agree. They are the absolute most fucking pretentious band to ever exist. I mean, really, $12,000 for front-row tickets to a concert? And aren't they trying to support the poor, starving people around the world? Argh.
Anyway, most alt. rock bands after 1990 fit into this category. After the grunge movement got more popular, it became stale very quickly. Grunge was pretty stale to begin with.
