H.A.M.," the first offering from Kanye West and Jay-Z's forthcoming collaborative album "Watch the Throne," premiered online just after midnight on Tuesday morning (Jan. 11), debuting on a dedicated Facebook page for the single.

Listen: Kanye West and Jay-Z, "H.A.M." here (requires Facebook account).

Over a menacing production by Lex Luger (Rick Ross' "B.M.F.," Waka Flocka Flame's "Hard in Da Paint") highlighted by dramatic strings and sampled operatic vocals, the hip-hop heavyweights trade boasts about power, women and wealth and proclaim themselves to be going "H.A.M." -- or "Hard As a Mothaf**ka," as they chant rapidly in the chorus.

"Got'em jumpin' out the building/Watch out below/A million out the door/I'm about to go, H.A.M.," West raps on the track, while Jay-Z spits, "I swam waters with great whites/Y'all mothaf**ckas would've been chewed/I hustle with vultures late night/Y'all mothaf**kas would've been fooled."

"H.A.M." is the lead single from West and Jay-Z's "Watch the Throne" album, which was originally slated to drop this week but is now reportedly due in March. The track was set to premiere on the same day Britney Spears' new single "Hold It Against Me," but the latter ended up hitting the net on Monday and averting a direct face-off between two hotly anticipated songs.
