Epic Records, Atlantic Records, and Def Jam all competed to sign Wale. On May 30, Wale released his fourth mixtape"The Mixtape About Nothing", heavily produced by Best Kept Secret. Wale said that the television show "Seinfeld" inspired "The Mixtape About Nothing": "the TV show's 'honest dialogue' mirrors his lyrical style, which frequently references pop culture and politics while avoiding gangster-rap bluster". After signing with Interscope, Wale began recording tracks for his major label debut: in a 2008 interview with "Express", a newspaper published by the Washington Post Company, Wale announced that he was recording a song with Chrisette Michele called "Shades", which discusses inter-black racism. Wale also appeared on Interscope label mate DJ Greg Street's single "Dope Boys" which samples Hip Hop classic T.R.O.Y. alongside Lupe Fiasco and Kardinal Offishall. Rapper Young Chris of rap duo Young Gunz also began plans for a collaboration mixtape with Wale. On June 19, 2009, Wale released his fifth mixtape, "Back to the Feature", on which eleven of the tracks were produced by 9th Wonder, with contributions also coming from Mark Ronson and others. The album's title, a play off the name of the movie "Back to the Future", referred to the fact that a lengthy list of rappers joined Wale on the songs, including K'naan, Tamere Guess, Talib Kweli, Joell Ortiz, Beanie Sigel, Curren$y, J. Cole and Bun B. The mixtape received positive reviews from "Vibe" magazine and website Pitchfork Media, but Colin McGowan of "Cokemachineglow" commented that it represented neither "a step forward or back [for the artist] so much as shouting-in-place. " Wale did a guest performance on "Change", a song by the Australian singer-songwriter Daniel Merriweather. It was written by Merriweather and Andrew Wyatt and produced by Mark Ronson. It was released on January 30, 2009, in the United States and Canada, and February 2, 2009, in the UK (where the song peaked at no.8). The song is included on Merriweather's album "Love & War". On September 13, Wale, alongside the DC-based musicians of UCB (Uncalled 4 Band)- The Board Administration artists, served as the official house band for the 2009 MTV Video Music Awards.
