After hearing Dallman's cover of Britney Spears's "Gimme More", producer Rachel Alina suggested releasing an EP of Spears's songs to bring attention to his music.

"Toxic" is a song recorded by American singer Britney Spears for her fourth studio album "In the Zone" (2003).  The song released on January 13, 2004, by Jive Records, as the second single from "In the Zone".  The song was originally offered to Kylie Minogue for her ninth studio album "Body Language" (2003), but she rejected it.  After trying to choose between "(I Got That) Boom Boom" and "Outrageous" to be the second single from "In the Zone", Spears selected "Toxic" instead.  A dance song with elements of bhangra music, "Toxic" features varied instrumentation, such as drums, synthesizers and surf guitar.  It is accompanied by high-pitched Bollywood strings, sampled from Lata Mangeshkar and S. P. Balasubrahmanyam's "Tere Mere Beech Mein" (1981), and breathy vocals.  Its lyrics draw an extended metaphor of a lover as a dangerous yet addictive drug.  The song has received acclaim from music critics, deeming it the strongest track of "In the Zone", and praised its hook and chorus.  "Toxic" won Spears her first and only Grammy Award at the 2005 ceremony in the category of Best Dance Recording.
