"Birthday" is a song by the English band Disclosure and American singer-songwriters Kehlani and Syd.
It was released as the sixth single from the duo's third studio album Energy on 26 August 2020.
"It has definitely stood the test of time and deservedly made the cut.
And the addition of Kehlani just took it to the next level and turned into a fire duet.
Syd and I were going through a similar thing at the time, trying to work out if it was cool to call your ex to say hi or is it too awkward / mean to do so out of the blue?
