I do agree with Mike though with the exception of AFI and Dashboard Confessional...I do like them. And P!ATD if you consider them emo.
I don't like any other ones.
I am way too indecisive for this game so I'll just name the tops...and cheat because I'm sure a number of these don't count as bands from todayBUT they'll outlast almost anyone from "today".
I agree with what you said about Nickelback and VR, Mike. Both are great bands. Nickelback just plain sounds good. And VR sounds like Guns N' Roses, which is always a good thing.
Um, is it bad that the only vaguely-current rock band I like and can name off the top of my head is U2? I don't really know that they would count as a band of today. :[
