Return of College Rock

An article in PopMatters asks if the resurgence of 80's and 90's college and art rock bands (Pixies, Mission of Burma, Morrissey) is good for music. I ask: Were the resurgences of Johnny Cash and Loretta Lynn good for music? When I throw Murmur or Surfer Rosa or Daydream Nation into the CD player, I hear music as edgy and fresh as anything on the radio today. Let's give them their airplay, and throw in a good dose of Modest Mouse, Franz Ferdinand, and the Strokes, and a sprinkling of the true underground to whet our appetites for more. Good music begets good music, and crap begets crap.
