A propos of this thread, I have a very large music collection, and consequently find that there are things in there that I have ignored or overlooked since I first bought them.
I recently purchased a great book:
The Mojo Collection: The Ultimate Music Companion
It goes through the last 50 years, chronologically and pics the best albums from each year, gives a 1 page summary of the key points about the record and a short review. It's a great read, and fun to dip into.
As I read through it, I was gratified to find that from its ~850 pages I had about half of the records it recommends, which got me to thinking.
So last week, I added every album it recommends which I own a copy of to a play-list on my iPod.
It's really rather good.
