"Don't Let Me Down" is a song recorded by British singer-songwriter Leona Lewis for her second studio album Echo (2009). Lewis co-wrote the song with Mike Elizondo, James Fauntleroy, Justin Timberlake and Robin Tadross. It was produced by The Y's and co-produced by Elizondo. Lewis and Timberlake carried out the vocal production. Having wanted to work with Timberlake for a long time, the collaboration came to be after he had asked Lewis to perform at a charity concert he was holding in Las Vegas in October 2008. It was reported that they were going to cover Dolly Parton's song "I Will Always Love You" as a duet, however they worked together on new songs for Echo instead, and "Don't Let Me Down" was created. Lewis revealed that her cover of "Run" inspired Timberlake.
