If you ever wanted to know what the greatest private collection of music in the world looks like, look no further, this has got to be it. There are more minutes of music in this collection than a human life span, consider this:

From Thomas Edison to American Idol, this is the complete history of the music that shaped and defined five generations. 3 million records and 300,000 CDs containing more than 6 million song titles. 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.

The seller is not asking for $50 million, however, bidding starts at a meager $3M, so the collection really is going for a song (pardon the terrible pun). The seller is looking for a suitable home for this outstanding collection, which would include a library, university or some other type of institution where it can be enjoyed. He desires that the collection be kept intact, but it is possible for the buyer to sell duplicate copies to recoup some of the expense. There are thousands of duplicate copies in the collection.
