The album includes guest appearances by the rapper Ty Dolla $ign and the singers MNEK and Wizkid.

The album's launch date was pushed back multiple times before it was ultimately released in March 2017.

To further promote the album, Larsson made several television appearances and live performances and embarked on the So Good World Tour from October 2017 to March 2018.

So Good received generally positive reviews from music critics upon its release, who complimented the album's production and Larsson's vocal performance.

During an interview with Digital Spy, Zara confirmed that each song on the album was written and produced by a different production team.

After several delays, Larsson released the artwork of the album on her social media on 3 February 2017, and So Good was made available for pre-order that day.

[13] It was an international success, peaking within the top 10 in several countries including the United Kingdom, Australia, Germany and Spain.

[25][26] Its official music video, directed by Emil Nava, was premiered via Larsson's Vevo account on 30 September 2016.

[28] On 27 January 2017, the title track "So Good" featuring Ty Dolla $ign was released as the fifth single from the album.

The official music video for the song, directed by Sarah McColgan, premiered on 3 February 2017 on Larsson's Vevo channel.

[33][34] The music video, directed by Clean Bandit's members Grace Chatto and Jack Patterson, premiered the same day.

On 12 May 2017, "Don't Let Me Be Yours", a song written by Ed Sheeran, was released as a single in the United Kingdom and was later promoted in Australia.

[39] Harriet Gibsone of The Guardian gave the album a three-star rating out of five, describing the album as "sugar-soaked postmodern pop", saying Larsson is like a "Rihanna-doting teen gatecrashing a tropical house party, gun fingers blazing, and her sugar-soaked songs are imbued with honesty".

[4] Nick Levine from NME gave the album four stars out of five, saying how the "big hits you know are obviously brilliant", but describing some of the "ballads towards the end" as "dull".
