Worlds largest music collection

For a music collector, having a secret downstairs cellar with a collection like the one above is a wet dream.
Legally blind and fighting diabetes, Mahwinney is reluctantly parting with his life's work, setting a goal of March 1 to unload this once-in-a-lifetime stash. The contents of the auction are quite amazing.
It's the undisputed largest collection of recorded music in the world. About half of the recordings are new and never played, and every genre of 20th century music is represented. There are countless rare recordings worth hundreds, or even thousands of dollars each on the collectibles market. Organized and cataloged, the collection is meticulously maintained and housed in a climate-controlled warehouse. The estimated value of this amazing collection is more than $50 million.
