Quick -- someone with a time machine travel to 1991! We need you to tell a Guns N' Roses fan still trying to wrap their heads around the just-released 'Use Your Illusion' albums that it will be nearly two decades before the band releases another collection of new music.

While you're at it, tell them GN'R would reportedly spend as much as 13 million dollars crafting this LP -- don't use the "Dr. Evil" voice, they haven't seen that film yet. Then, show them a picture of the band's 2008 lineup, and offer them a new car if they can identify more than three members of the group. Finally, play them the sprawling, somewhat spotty record and ask if it was worth all that time, money and turnover. Oh, and get their reaction on YouTube, will you?
