The new Eminem album features a sequel to his infamous hit "Stan", according to the producer.
Swizz Beats has been working on Relapse, the rapper's first record since 2004's Encore, in recent months, alongside Dr Dre.
He says one of the songs, which carries the working title "Stan 2" is a follow-up to the ground-breaking 2000 smash.
Beatz, who is understood to have five songs in the reckoning for the new album, said the track is totally genius.
Speaking about the rest of the recordings, he commented: "Different sound, different mindframe. He's clear. But it's the Eminem that you missed, that you loved, that you need, especially right now in the industry, going into '09. He's coming back to take the cake."
Relapse is now scheduled for release in early 2009.
