The Bellrays' lead singer Lisa Kekaula, who has previously appeared on Basement Jaxx's 2004 single "Good Luck", also co-wrote and contributed the song's main vocal.

Its accompanying music video, directed by Mat Kirkby, features a Queen Elizabeth II look-alike drinking and fighting in Soho, London.

In March 2005, Basement Jaxx released their first greatest hits album The Singles, which included two new songs, "U Don't Know Me" and "Oh My Gosh".

[6] According to Daniel Montesinos-Donaghy of Thump, "U Don't Know Me" is a rock song that features beatboxing, drums, xylophones, a keyboard solo and backing vocalists that "offer more joyful 'woo's than you would expect".

[4] Writing for the Seattle Weekly, Michaelangelo Matos said "U Don't Know Me" sounds like an outtake from the duo's last album, Kish Kash (2003).

He felt the song was "nowhere near as euphoric" as Basement Jaxx and Kekaula's previous collaboration, "Good Luck", and that the track was only their rock songwriting "exercise".

[18] A scene from the video which shows the look-alike groping a lapdancer, led MTV in the United Kingdom to broadcast it only after the 7:00 pm watershed to adhere to Ofcom regulations.

"[17] However, a spokeswoman for MTV told the BBC that the clip was, indeed, a "great video", and they were planning on giving it heavy rotation in evening schedules.

[16] Buxton told The Record: "MTV wasn't allowed to play it in the daytime in the UK at the beginning but yeah, people seem to enjoy it.
