Eminem's Shady Records imprint is celebrating 15 year in the game and as an appreciation gift, the rapper will serve fans with a 66-track mixtape.

While the tape will arrive after the 'Shady XV' album, it will give listeners the chance to hear songs that didn't make that final project's tracklist. “You guys gave me 130 records,” DJ Whoo Kid said to Shady Records' co-founder Paul Rosenberg during an interview with Rap Radar. “Physically, you can’t fit all of them on 80-minute CDs, so we had to do a double disc.”

Songs could feature any of the Shady acts on the roster including Slaughterhouse, Yelawolf, D12, Obie Trice, Bad Meets Evil and Em's longtime friend 50 Cent.

Whoo Kid also revealed that the new nostalgic mixtape clocks in at a little over three hours and will feature a mixture of songs that have been previously released. This effort will just have all of the material together for the first time.

“We figured since there’s so many people that are gonna be saying, Ah, why didn’t this song make it [on the album]? Rosenberg told Rap Radar, "Why didn’t that song make it? We’ll just do something to please everybody.”

'Shady XV' arrives Nov. 24.
