So the 2014 Rock and Roll Hall of Fame nominees have been released. Maybe you're a music nerd who knows all the acts' catalogs front to back. Good on you! But if there are a few artists you're only sorta kinda or not at all familiar with, we got you. We put together a few tracks from each of the 16 nominees to turn you into an instant Hall of Fame expert in a few hours. Listen now. Thank us later.
