The Eagles and Paul Simon are among the records owned by the late Princess which are to go under the hammer at auction.
The personal library - which includes several albums with the Princess's name scrawled in pen on them - contains a variety from Bob Dylan's Hard Rain to several Beethoven classics.
It also includes country and western legend John Denver's Rocky Mountain High and The Eagles' Greatest Hits.
The late princess had personally signed the collection of 19 albums as a youngster to prove to other members of her family they belonged to her - in case they failed to return them if they borrowed any.
It is believed her favourite was the soundtrack to Franco Zeffirelli's 1968 film Romeo and Juliet.
In 2002 Prince William reclaimed several of his mother's albums after they were allegedly stolen.
Two years later the vinyl collection was sold to a mystery buyer for just £6, along with other items of royal memorabilia, at a boot sale at Cholmondeley Castle in Cheshire which raised money for the Princess Trust and the North West Cancer Research Fund.
At the time veteran DJ Paul Gambaccini, who was hired to catalogue Diana's childhood record collection after her death, said: "The records would fit very snugly into the collection I saw at St James' Palace.
"It was custom for the Spencer children to put first names on records to make it clear which record belonged to which child."
The LPs are now being sold online by PFC auctions, which is also selling a slice of Prince William and Kate's wedding cake.
The auctioneer is expecting the albums collections to fetch several thousands of pounds.
The list of albums includes: Carmen, Romeo and Juliet, Brahms Hungarian Dance, Beethoven Pastoral Symphony, La Fille Mal Gardee, Elgar Enigma Variation, Paul Simon - Still crazy after all these years, Bob Dylan - Hard Rain, John Denver - Rocky Mountain High and Eagles Greatest Hits.
