Question: What diss song was a response to Mobb Deep, featuring the group the Outlawz?
Context: The Infamous (stylized as The Infamous...) is the second studio album by the American hip hop duo Mobb Deep.  It was released on April 25, 1995, by Loud Records.  The album features guest appearances by Nas, Raekwon, Ghostface Killah, and Q-Tip, who also contributed to the production and mixing of the album.  Embedded with hyper-visual lyricism, dark soundscapes, gritty narratives, and hard beats, it marked Mobb Deep's transition from a relatively unknown rap duo to an influential and commercially successful one.  Most of the left-over songs from the album became bonus tracks for Mobb Deep's "The Infamous Mobb Deep" album (2014). Hell on Earth is the third studio album by East Coast hip hop group Mobb Deep, which was first released on November 19, 1996, on Loud/RCA/BMG Records.  The album is largely a continuation of Mobb Deep's previous album, the critically acclaimed "The Infamous".  The album is produced by Mobb Deep and also features guest appearances by emcees Nas, Raekwon, Method Man, and frequent collaborator Big Noyd.  The album stands out for its acclaimed singles "G.O.D. Pt.  III" and "Hell on Earth (Front Lines)," as well as "Drop a Gem on 'Em," a response to 2Pac's diss track "Hit 'Em Up."  A promotional single, "Still Shinin'", was released earlier that year and later added to the album.  The album, one of the earliest enhanced CDs, also contains an additional track ("In the Long Run") that at the time, had to be unlocked with the use of a computer. "Hey Luv (Anything)" is the second single from Mobb Deep's "Infamy" album.  The song features 112 & the music video was directed by Little X.  This song is also included on the B-side of "Get Away", the group's next single.  It is the Mobb Deep's highest charting song to date, debuting at #58 on The Billboard Hot 100 music chart. The Infamous Mobb Deep is the eighth and final studio album by American hip hop duo Mobb Deep, which is composed of Havoc and Prodigy.  The album was released on April 1, 2014, by Prodigy's Infamous Records and Sony's RED Distribution.  "The Infamous Mobb Deep" is a double album that consists of one disc of new original music and another of unreleased tracks from the recording sessions from their second studio album "The Infamous" (1995).  The album has been in development since 2011, but was delayed by a feud that occurred between Havoc and Prodigy during 2012.  However, they shortly reconciled. "The Roof" is a song by American singer and songwriter Mariah Carey, taken from her sixth studio album, "Butterfly" (1997).  It was released as the third single from the album in Europe, on March 20, 1998 by Columbia Records.  Similar to the treatments of "Butterfly" and "Breakdown", "The Roof" received a limited worldwide release due to Carey's conflict at the time with Sony.  The song was written and produced by Carey and Trackmasters, and is built around a sample from "Shook Ones part II" by Mobb Deep.  The song's lyrics recount an intimate roof-top encounter between lovers, and how the memory affects the protagonist.  The extended remix features a rap verse by Mobb Deep; both versions were well received by contemporary music critics. "Outta Control" is a song by American hip-hop artist 50 Cent, recorded for his second studio album, "The Massacre" (2005).  The song features production from Dr. Dre and Mike Elizondo.  A remixed version of the song (although it bears no resemblance to the original) was released as the fourth and final single from "The Massacre", although it is only included on the re-released version and replaces the original version.  The remix is also produced by Dr. Dre and Elizondo and features a guest appearance from hip-hop group Mobb Deep.  It also appears as a bonus track on Mobb Deep's seventh studio album "Blood Money" (2006). "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. The Infamous Archives is an album by Queensbridge hip-hop duo Mobb Deep on March 13, 2007.  The album consists of previously unreleased tracks.  The first disc contains Mobb Deep's "Back from a Hiatus" mixtape from 1998.  Rappers such as Sticky Fingaz, 50 Cent, Snoop Dogg and Busta Rhymes are featured.  The song "In the Long Run", Prodigy spoke about the altercation between him and Keith Murray.  In Prodigy's book, he stated this release wasn't authorized by the group. The Dunn language or Dunn lingo is a style of East Coast hip hop slang popularized in the mid-1990s by rappers such as Queensbridge's Mobb Deep, Tragedy Khadafi, Capone-N-Noreaga, Nas and AZ, and to a lesser extent Raekwon and Ghostface Killah of the Wu-Tang Clan.  While much of the slang had already been introduced by this point, the term "Dunn language" was first recorded in Mobb Deep's 1999 single "Quiet Storm", in which Prodigy raps: "you's a dick blower, [you] tryin' to speak the Dunn Language? / "what's the drilly" with that though?  "It aint bangin"/ you hooked on Mobb phonics, Infamous 'bonics." Life of the Infamous: The Best of Mobb Deep is the greatest hits album from Queensbridge rap duo Mobb Deep.  It contains songs dating back to their 1993 debut album, "Juvenile Hell", through their 2004 album, "Amerikaz Nightmare".  No "Blood Money" songs are on the album since those tracks are owned by Universal Music Group, not Sony Music Entertainment, the label that released this album.  The disc includes "Blood Money" and "Go Head", two previously unreleased tracks.  "Keep It Thoro" is the only song featured on a non-Mobb Deep album (Prodigy's "H.N.I.C.").
