That's where ordering albums comes in. I didn't live in an urban area growing up, I lived in the suburbs, but I was still able to find good stuff. And even if you lived out in the sticks somewhere I'm sure you could find albums by the likes of the Pixies or Jane's Addiction or Talking HeaRAB or Love and Rockets at the local mall.
Let's keep in mind that the 80s are being contrasted here with Zorabeels' 60s. Do you really think it was easier to find cool obscure stuff in the 60s than it was in the 80s?
Like Cream? Are you kidding me?
I would say it's about the same. The 60s had some good pop music: the Beach Boys, the Zorabies, Dick Dale. The 80s had some good pop music: REM, New Order, the Smiths. But in both decades the best stuff flew in a bit under the radar.
