The lyrical content of the song is said to be influenced by Labrinth's anxiety over his second album, with the artist offering the following overview of the track's origins:
It doesn't sound like anything I've done before. It made me go back and look at all the other records again and be like, "Ah, maybe it needs to sound more exciting? Maybe it's not poppy enough? Or commercial enough." I started doing all these things that, after a great piece of work has been made, it starts to fuck it up. I had a bit of an anxiety attack, but after that I was just like, the only answer is to do what is right – just let go and let everything happen the way it is going to happen. That is where the record kind of came from.[2]

I wanted an opening statement to my second album and I put extra pressure on myself to come up with that".[3]
Critical reception
Upon release, "Let It Be" received generally positive reception from critics. Writing for 4Music, reviewer Jessica Lever described the track as "fresh, catchy and upbeat".[5] 4Music later called the song a "sexy new soul jam".[6]
Idolator contributor Rachel Sonis explained that "While it might not be a party-starter like his Tinie Tempah-assisted club banger "Earthquake", ["Let It Be"] not only lets his sultry pipes shine through, but also shows a real maturation for the 25-year-old English crooner".[7] Rachel Sonis of Idolator described the video as "dizzying" and "eerie",[7] while a news story by radio station Kiss dubbed it "stripped back".[8]
Music video
The music video for "Let It Be", directed by duo Us (Luke Taylor and Christopher Barrett),[9] was released on 27 August 2014.
