The song was recorded in 2005 at Wandsworth Studios which was shown on Stevens' television documentary "Rachel Stevens: My World" and was one of the first songs that she recorded for the album. Stevens stated in the documentary that the song had helped her "find her sound for the album". The track was mixed at 21 Studios in London for its release.
Critical reception and release
The song received positive reviews from music critics who praised its production and Stevens' vocals, with some labelling it as "much ahead of its time". Some critics described it as the "I Will Survive of the 21st century" due its lyrical content in which Stevens declares that she has "made it on her own again" and will "feel so good" after ending a relationship. "So Good" was released on 4 July 2005 under two CD single formats and a digital download in the United Kingdom and Europe. The first CD contains a radio edit of the track and a Milky Vocal Mix of Breathe In, Breathe Out and the second CD also contains a radio edit, an Aurora Vocal Mix, a previously unreleased track "Never Go Back" and an enhanced section that contains the music video, karaoke video and game.
Commercial Performance
After Stevens' previous single "Negotiate With Love" peaked at number 10 on the UK Singles Chart, expectations were high for "So Good" to chart higher due to stronger radio airplay and receiving more positive reviews. However, it failed to do so and also peaked at number 10 with first-week sales of 11,750 copies, lasting eight weeks on the chart, a week longer than "Negotiate With Love". To date, it is Stevens's last single to peak within the top 10.
Music video
Prior to the video's release, a behind the scenes for the video was shown on GMTV. The music video for "So Good" was directed by Cameron Casey and was filmed in mid-2005 at a studio in London. The video features Stevens with a group of four men in a dark metallic room, dancing in front of a wall of flashing coloured lights. In some scenes, Stevens is lying on a circular shaped stage with the flashing lights in the background and other scenes show the four men dancing individually on the stage. Throughout the video, there are many close-up shots of Stevens with the lights behind her. During the bridge of the song, Stevens and the four men do a fast robot styled dance routine. In the video, she has a braided hairstyle and is wearing a black ballerina-like dress and sports pink mid-hand gloves that gained a cult following because of the British pop website Popjustice, where they were the subject of a front-page article and a special message boarddiscussion forum. In an interview with GMTV, Stevens stated that the pink gloves were to give the outfit some colour and also due to the hand orientated dance routine.
