An accompanying music video was directed by Scott Lyon and shows Beckham satirising her life as a celebrity.

[6] "Let Your Head Go"/"This Groove" remains Beckham's last single release to date, as she was eventually dismissed from Telstar when the company became bankrupt, and decided to give up music to focus on her fashion career.

[15] Similarly, Jon O'Brien from Billboard thought that the song was the "kind of irresistible dance-pop that resurrected Kylie Minogue’s career just a few years prior".

[9] According to David Sinclair in the book Spice Girls Revisited: How The Spice Girls Reinvented Pop (2008), the track had an upbeat Europop feel and "boasted a tune with something of the Kylies about it"; he also noted the "stunning banality" of the lyrics, which find Beckham singing, "And when it feels so good / I can almost lose my mind / Ooh, it makes me crazy, every time".

[18] For O'Brien of Billboard, it "turned out to be her finest hour", mentioning that it was "just a shame she only found her sound when it was too late" with the material, referencing the fact that Beckham abandoned her music career shortly upon its release.

[14] In the same vein, Myers from the Official Charts Company thought the track was "a pretty good way to end [her] pop career".

[19] Music Week staff described both "Let Your Head Go" and "This Groove" as "inoffensive pop/dance/R&B hybrids, treated to an ultra-sleek production that makes the most of her vocal proficiency".

[1] In the UK, "Let Your Head Go"/"This Groove" faced competition with Sophie Ellis-Bextor's "I Won't Change You"; they were previously involved in a much publicised chart battle in 2000, when their singles were also released in the same week.

[a][9][21] Beckham's single entered the UK Singles Chart at number three on the week ending on 4 January 2004, behind Michael Andrews and Gary Jules' "Mad World", and Ozzy and Kelly Osbourne's "Changes", despite weeks of intense publicity prior to its release, selling 29,505 copies;[22][23][24] Ellis-Bextor's song entered at number nine.

[16] In the same vein, Billboard's O'Brien deemed it a "inspired satirical video" which "proved that, despite her deadly serious image, Posh Spice certainly wasn’t averse to poking fun at herself".

[14] Myers of Official Charts Company felt that the clip "showed Victoria sending up her fashionista diva image to great effect.

"[9] Ben Kelly of Attitude said that the material "raises the stakes as she raves it out in a maniacal flower-chopping scene which gives way to the most pouty section in a music video ever".
