Encore The Black Album FUCK THE ROCK VERSION, THIS IS THE REAL SHIT Lyrics by Will Tian Thank you, thank you, thank you, you're far too kind Now can I get an encore, do you want more Cookin raw with the Brooklyn boss So for one last time I need y'all to roar Now what the hell are you waitin for After me, there shall be no more So for one last time, nigga make some noise Who you know fresher than Hov'? Riddle me that The rest of y'all know where I'm lyrically at Can't none of y'all mirror me back Yeah hearin me rap is like hearin G. Rap in his prime I'm, young H.O., rap's Grateful Dead Back to take over the globe, now break bread I'm in, Boeing jets, Global Express Out the country but the blueberry still connect On the louvre but the yacht got a triple deck But when you Young, what the fuck you expect? Yep, yep Grand openin, grand closin God damn your man Hov' cracked the can open again Who you gon' find doper than him with no pen just draw off inspiration Soon you gon' see you can't replace him with cheap imitations for DESE GENERATIONS Can I get an encore, do you want more What the hell are you waiting forrrr?*sighs* Look what you made me do, look what I made for you Knew if I paid my dues, how will they pay you When you first come in the game, they try to play you Then you drop a couple of hits, look how they wave to you From Marcy to Madison Square To the only thing that matters in just a matter of years As fate would have it, Jay's status appears to be at an all-time high, perfect time to say goodbye When I come back like Jordan, wearin the 4-5 It ain't to play games witchu It's to aim at you, probably maim you If I owe you I'm blowin you to smithereeens Cocksucker take one for your team And I need you to remember one thing I came, I saw, I conquered From record sales, to sold out concerts So muh'fucker if you want this encore I need you to scream,'til your lungs get sore This man is MADE!
