Second best? Well it will probably never be settled - is it second best, or the best? I just know that Dark Side of the Moon and Wish You Were Here are two of the greatest recordings ever made. Classic, timeless, genius, brilliant, beautiful, all the terms used to describe great music apply. A lot of talent and great music came out of the '60s and '70s, but none any better than this.
GRAB IT! Then play it loud and on the best headphones or stereo equipment you can find!
And sorry, dontpanicbobby, it is Wish You Were Here.
