Tupac ShakurWhen Tupac Shakur died in 1996, he left behind so much unreleased material that new songs continue to pop-up even 15 years after his death.

While many posthumous Pac tracks were uplifting, such as “Changes” and “Til the End of Time,” two new tracks hit the Internet this week, showing the rapper’s other side, in which he disses his adversaries.

On the tracks, “NY 87” and “Watch Yo Mouth,” Pac takes aim at several east coast rappers.

While “Watch Yo Mouth” is being called a new track, it surfaced online two years ago (according to MTV), but the new version boasts an alternative beat. On it, Tupac goes hard at the legendary Dr. Dre.

“He ain’t made a beat in six years, swear he the sh** / Won’t get no record sales suckin’ Nas’ d***.”

Later, he throws shots at Nas, as well as De La Soul, Wendy Williams, Diddy and the Notorious B.I.G. Despite the lyrical insults, Pac downplays the much-hyped East Coast/ West Coast beef of the mid-1990s by chanting, “For my n****s on the east side” throughout the song.

On “NY 87”, Pac gets help from The Dogg Pound (Daz and Kurupt) and Threat; and DJ Quik kicks things off with a monologue, stating: “Them n****s on the East is the enemy.” Kurupt and Daz take the first two verses, and on the last verse, Pac doesn’t drop any names.

Instead, he spits: “Move motherf***ers ’til they feel me / It’s West Coast n****, f*** New York, now did everybody hear me?”

Both songs seem to have been recording during Pac’s Death Row days in 1996, at the height of his feud with Diddy’s Bad Boy record label, the Notorious B.I.G., and other New York artists.

Why these tracks were released now is still unknown.
