It was released to digital retailers on 16 June 2017, and later it was the lead single from Ezra's second studio album Staying at Tamara's (2018).

[7] On 7 June 2017, Ezra performed five new songs in Bath on his "Top Secret" tour, with "Don't Matter Now" being one of them.

[11][12] Andrew Trendell of NME regarded the song as an "anthemic showcase of Ezra's songcraftsmanship" and the "cathartic ode to being honest about how you're really feeling".

[1] Gabriel Aikins of Substream Magazine wrote that the song "combines Ezra's trademark acoustic guitar with horns on a track about letting go of the things that don't matter to more fully enjoy life".

[6] Kirstie Sutherland of Redbrick wrote: 'Don't Matter Now' is typical George – happy-go-lucky, care-free and just really bloody lovely.
