BT asked JC Chasez to appear on "Somnambulist (Simply Being Loved)", after the former musician produced NSYNC's 2001 song "Pop".

[1] "Somnambulist (Simply Being Loved)" is the lead single from BT's fourth studio album, Emotional Technology (2003),[2] and was released in August 2003.

[5] "Somnambulist (Simply Being Loved)" peaked at number 98 on the US Billboard Hot 100 chart dated September 13, 2003, where it remained for three weeks.

[16] Michael Hamersly of Miami Herald compared the "quirky" sound in "Somnambulist (Simply Being Loved)" to Star Wars character R2-D2 and commented that the chorus is "spiritual".

[17] However, Los Angeles Times writer Tommy Nguyen opined that it is "hopelessly moderate" in BT's attempts for a "[vague] crossover sound".

[20] Writing for PopMatters, Andy Hermann criticized the repetitive lyrics and described BT's foray into the pop genre as "drivel".
