After winning the fourth series of German reality television show Popstars in 2004, Nu Pagadi recorded "Sweetest Poison" and released it as their debut single on 13 December 2004.

Written by Jörn-Uwe Fahrenkrog-Petersen, Lukas Hilbert, and Rea Garvey (as "R. G."), the song became a number-one hit in Germany, Austria, and Switzerland and was included on the band's only studio album, Your Dark Side, the following year.

On 8 December 2004, during the concluding episode of Popstars series four, Patrick Boinet, Kristina Dörfer, Markus Grimm, and Doreen Steinert were chosen as the four winners of the competition after singing "Sweetest Poison", written by Lukas Hilbert, Rea Garvey (as "R. G."), and Nena keyboardist Jörn-Uwe Fahrenkrog-Petersen.

The track spent 17 weeks on the Austrian chart and was certified gold by the International Federation of the Phonographic Industry (IFPI) for selling over 15,000 copies.

[9] After "Sweetest Poison", Nu Pagaldi released their second and final single, "Dying Words", which stalled at number 22 in Germany and failed to reach the top 30 in Austria and Switzerland.
