"Westside Story" is the debut single by American rapper and West Coast hip hop artist the Game.
 The song was produced by both Dr. Dre and Scott Storch, and was co-written by Mike Elizondo, Dre, Storch, the Game and 50 Cent.
 It was released in 2004 as the lead single from Game's debut studio album "The Documentary".
 The song debuted at #99 and peaked at #93 on the "Billboard" Hot 100.
 It was an airplay-only release, thus no music video for the song was made.
 Rolling Stone's review of the album described this song as "a kind of L.A. version of "In da Club".
 The Game has stated that this song is a tribute to Tupac Shakur, with a direct reference to him, saying "I got +California Love+ fuckin' bitches to that Pac shit."
 The Game also makes references to Tupac's songs, "California Love" and "Against All Odds".
 Other references include: Nate Dogg, Tha Dogg Pound (D.P.G.) and their song "New York", Westside Connection, Michael Jackson and his album "Thriller", DJ Pooh and Kool G Rap.
 There is a remix featuring Snoop Dogg singing the hook and a version with both Snoop Dogg and 50 Cent on it.

Deaf Side Story is a musical based on "West Side Story", itself an adaptation of William Shakespeare's play "Romeo and Juliet".
 Takes place in New York City during the mid-1950s, the musical based on West Side Story explores the rivalry between the two gangs Jets and the Sharks, two teenage street gangs of different cultural backgrounds (Deaf and Hearing).
 The members of the Sharks from Puerto Rico are taunted by the Jets, a white working-class group.
 The young protagonist, Tony, one of the Jets, falls in love with Maria, the sister of Bernardo, the leader of the Sharks.
 The theme, music, and dances focus on culture problems.
West Side Story is the soundtrack to the 1961 film "West Side Story".
 Released in 1961, the soundtrack spent 54 weeks at No. 1 on Billboard's album charts, giving it the longest run at No. 1 of any album in history, although some lists instead credit Michael Jackson's "Thriller", on the grounds that "West Side Story" was listed on a chart for stereo albums only at a time when many albums were recorded in mono.
 In 1962, it won a Grammy award for "Best Sound Track Album – Original Cast" and Johnny Richards orchestrations of the movie score (on "Kenton's West Side Story") also winning a Grammy in 1962 for "Best Large Ensemble Jazz Album" further bolstering the popularity of the movie and soundtrack.
 In the United States, it was the best-selling album of the 1960s, certifying three times platinum by the RIAA on November 21, 1986.

 This was the only single from the album to not have the Parental Advisory sticker on its cover since the only profanity was the word "nigga" in the first verse.
 The song was mixed by Dr. Dre.
"Thug Love" is a song recorded by American rapper 50 Cent for his debut studio album "Power of the Dollar" (2000).
