Soulshock & Karlin have written and produced hits for many artists such as Brandy, Usher, Monica, Whitney Houston, Luther Vandross, Craig David and Sting in "Rise & Fall", and again 2Pac in "Me Against the World", "I Wonder If Heaven Got a Ghetto", "Old School", and "Baby Don't Cry (Keep Ya Head Up II)".
The duo took a break from working together in 2010 when Soulshock was asked to become a judge on the Danish version of The X Factor before becoming the in-house producer for the U.S. incarnation of the show.
While the future overseas looked bright, Soulshock & Karlin felt that the brand of R&B/hip-hop they specialized in was being overshadowed in Europe by dance and house music.
In 1999, Soulshock & Karlin enjoyed another number-one single with Whitney Houston's "Heartbreak Hotel", which received two Grammy nominations: Best R&B Song, and Best R&B Performance by a Duo or Vocalist.
Soulshock & Karlin produced the tracks "Rise and Fall" by Craig David and Sting; Blu Cantrell's "Don't Wanna Say Goodbye", Monica's "Breaks My Heart", "I Wrote This Song", and "What Hurts the Most", and the first single from American Pop Idol contestant Justin Guarini, "Sorry".
