To promote the song, Shelton's official website launched a contest where fans could upload pictures of themselves with their loved ones.

The lyrics pertain to the couple's personal relationship and describe being able to find happiness anywhere, which alludes to the consequences of the COVID-19 pandemic.

It also reached number two on the main Digital Song Sales chart in the US, blocked from the top spot by Taylor Swift's 2020 single "Cardigan".

[1][2][3] Following the impact of his previous collaboration with Stefani, Shelton commented: "Even though Gwen and I just had a single out, we decided that, under the circumstances, this year ... man, there's never been a better time for 'Happy Anywhere'.

[10] It marks Shelton and Stefani's fourth collaboration, following "Go Ahead and Break My Heart" (2016), "You Make It Feel Like Christmas" (2017), and "Nobody but You".

[11] In September 2020, Shelton's official website announced a contest where fans could upload pictures of themselves with a "description of the person that makes you happy anywhere"; the stories were then posted on a world map on the site.

[6] Stefani provides less vocals for "Happy Anywhere" than she previously did in "Nobody but You", and does not have a solo verse or chorus; however, she contributes to harmonies with Shelton.

[13] According to the song's sheet music published by Musicnotes.com, "Happy Anywhere" is set in common time and has a moderately slow tempo with 166 beats per minute.

[14] The key of the song is in A-flat major, with the pair's vocal range spanning from E♭4 to E♭5 in scientific pitch notation.

[30] The clip was produced by Todd Stefani, Gwen's younger brother, who was a guest at Shelton's Oklahoma ranch home during the COVID-19 pandemic.

[31] It was announced on July 20, 2020, that Shelton and Stefani would perform "Happy Anywhere" live during an episode of Today in the United States.
