Question: Hell on Earth included a diss track featuring what band?
Context: "Hit 'Em Up" is a diss song by rap artist 2Pac featuring his group the Outlawz.  It is the B-side to the single "How Do U Want It", released on June 4, 1996.  The song’s lyrics contain vicious insults to several East Coast rappers, chief among them, Shakur's former friend turned rival, The Notorious B.I.G., also known as Biggie Smalls.  The song was recorded in Los Angeles, California at Can Am Studios in May 1996.  Reporter Chuck Philips, who interviewed Shakur at Can Am, described the song as "a caustic anti-East Coast crusade in which the rapper threatens to eliminate Biggie, Sean Combs (Puffy), and a slew of Bad Boy artists and other New York acts."  The song was produced by long-time collaborator Johnny "J" and samples the bassline from "Don't Look Any Further" by Dennis Edwards and interpolates "Get Money" by Biggie Smalls group Junior M.A.F.I.A., which used the Dennis Edwards sample as well.  The song's chorus contains an interpolation of Yellowman's 1982 hit reggae single 'Zungguzungguguzungguzeng'.  The video, itself described as infamous, includes impersonations of Biggie, Puffy and Lil' Kim.
