It's a sub-genre of alternative that emerged after the height of the grunge scene. Most bands in the post-grunge era had only a few hits, and ended up on those BUZZ compilations. There are some really good bands that came out of this time, though. Some of the bands include:
Bush
Collective Soul
Everclear
Semisonic
Tonic
Filter
Foo Fighters
Live
Incubus
Harvey Danger (remember these guys?
)
Our Lady Peace
Stiltskin
The Verve Pipe
