From his basement studio at his mother's house, Sparks was able to convince major record labels that he ran a successful online radio show. Around the year 2000, he conducted interviews there with acts like Eminem, Common, Sean Kingston, Talib Kweli, the Wu-Tang Clan, Mobb Deep, the Clipse, and others. He ran the interviews on the radio station where he worked, Boston's Hot 97.7. Sparks was also able to accumulate freestyle raps and performances (usually over his own beats) from these artists that he would put into mixtapes. In 2002, he won the award for New Mixtape DJ of the Year at the Justo Mixtape Awards. By 2004, Sparks was hosting weekly radio shows on Hot 97.7, Baltimore's 92Q, and Hartford, Connecticut's Hot 93.7. He also hosted a syndicated hip hop show, "SmashTime Radio", through SupeRadio that aired in 40 cities. That year, he was also named the Radio DJ of the Year at the Mixshow Power Summit Awards.
