"Somnambulist (Simply Being Loved)" is a song by Brian Transeau, better known as BT, that was released as a single on March 20, 2003. The track quickly became the most successful track from the album Emotional Technology, and one of Transeau's biggest commercial hits. The album debuted at number one on the Billboard Dance/Electronic Albums chart. The song features background vocals by JC Chasez.

The song features BT's signature 'stutter edit' technique prominently in his vocals, largely contributing to the song's inclusion in the Guinness Book of World Records in 2003 for the largest number of vocal edits in a song (6,178 BIAS Peak edits).

The unmixed version of the song was featured in the North American music video game Dance Dance Revolution Extreme for the PlayStation 2. In the game the song was cut from its original version to roughly a minute and a half in length to fit the standard play length for songs in the DDR series. The main title of the song was displayed as "Simply Being Loved" with "Somnambulist" as the subtitle.

The song's music video features BT sleepwalking, magically changing the background to a city before he was in a nightclub. It ends with it being played backwards very fast.
