IS TUPAC ALIVE?????

Well its been 13+ years since the death of arguably the greatest rapper of all time,(imo he is)Since his death there has been reports of sightings and pictures..videos..and clues left in his legacy that points to him being alive.Well 13 years after he dies and the collapse of the old deathrow there has been tons of tupac leaks this year.

Now im no alive theorist,but There has been two tracks that have cought my mind that really has me thinking.Tupac featuring outlawz - War Gamez (Jay Z, Mobb Deep, Dr. Dre, The Firm Diss)and Tupac - Watch Ya Mouth(Unreleased)(Clip.

Both of these songs go hard as fuck,but thats besides the point.

WIKIPEDIA - THE FIRM

Released October 21, 1997

"How many broke down rappers got some sh*t to say...I bust on Bad Boy, Mobb Deep and murder The Firm/When you scream 'fake thugs' who the f*ck you mean/Get more C.R.E.A.M. than all of y'all/N*gga f*ck your team/Now Dre wanna switch sides/Tricks hide in war/Last year I shed tears but I don't cry no more/Plus Jay-Z tried to play me/He won't last long/Go ask King Sun how it feel to have your a** gone...Got shot five times, got outta jail on bail and sold five million. Sold more records than all you trick motherf*ckers put together. More than The Firm, more than Bad Boy, murdered Mobb Deep, more than all you b*tch made n*ggas." (War Gamez)
