The single was released in March 2002 in CD and vinyl format.

The match has frequently been criticized for possibly being staged, and the celebrity's later association with professional "Street Fighter" play has resulted in mixed opinions among the fighting game community. Lupe Fiasco's The Cool (commonly referred as The Cool) is the second studio album by Chicago-native rapper Lupe Fiasco.  It was released on December 18, 2007, by 1st & 15th Entertainment and Atlantic Records.  Recording sessions took place during 2006 to 2007, with Lupe Fiasco himself, alongside Charles Patton (Chilly) serving as the records executive producers.  The concept album, "The Cool" was based upon the song and a title character from his debut album, "Food & Liquor" (2006).  The album features guest appearances from Gemini, Snoop Dogg and Matthew Santos, while the production was provided by Patrick Stump, Soundtrakk and Unkle, among others. "Shining Down" is a song by Lupe Fiasco.  It was intended to be the first single of "Everywhere", the first of three CDs of Lupe Fiasco's triple album, "Lupe Fiasco's LupE.N.D." , but because of its release being withheld, there was speculation circulating that it may be the first single of his third album, "Lasers".  The song, however, was only included in the iTunes deluxe version of the album and was considered a promotional single.  The song is produced by Soundtrakk and features Matthew Santos, in the same collaborative manner in which the lead single "Superstar" was composed for Lupe's critically acclaimed second album "Lupe Fiasco's The Cool".
