My first pick as a good pop rock (band), within the last decade or so, would be 3 Doors Down, I just personally like their style of pop rock, although most popular catagory is: hard rock, southern rock, alternative rock, & post-grunge, seems to stay very popular within the (weekend) club scene.
I also classify Nickelback in the pop genre more so, than either of the rock or metal genre's.
