Now how old do you feel? To celebrate the label's 15th anniversary, Eminem is releasing a two-disc compilation called ShadyXV, and he's just released the tracklist.

The first disc will feature a selection of all new tracks, including songs by Slaughterhouse, Bad Meets Evil, Yelawolf and D12. Eminem recruits two powerful divas, Sia and Skylar Grey, to join him on "Guts Over Fear" and"Twisted," respectively.

Of particular interest is "Detroit Vs. Everybody," a major hometown posse cut featuring Detroit MCs Royce Da 5'9″, Big Sean, Danny Brown, DeJ Loaf and Trick Trick. One imagines the song is the collaboration Big Sean and Eminem have teased in the past.

On the the second disc, Eminem has collected some of his labels biggest hits, including his own "Lose Yourself," 50 Cent's "In Da Club," and D12′s "Fight Music."
