While I'm pretty much not a listener of commercial, mainstream rock, mostly because I listen to pretty much worship music or Christian rock/rap/etc only, I do sometimes venture out into secular music, because I'm a sucker for pop rock and for good music.
One bands I've recently heard is Throwing Gravity - a really good band that I think has a promising future. The style of this band is the same style I tend to write music in- sometimes heavy, all catchy, and built on a solid hook.
