2019 oscar award sade adu shortlisted for best original song

I think there may be some confusion here!

Sade Adu is a legendary Nigerian-British singer-songwriter, but I couldn't find any evidence that she was shortlisted for an Oscar Award for Best Original Song in 2019 or any other year.

The 91st Academy Awards, which honored the best in film for 2018, took place on February 24, 2019. The nominees for Best Original Song were:

• "All the Stars" from Black Panther (performed by Kendrick Lamar and SZA)
• "I'll Fight" from RBG (performed by Jennifer Hudson)
• "The Place Where Lost Things Go" from Mary Poppins Returns (performed by Emily Blunt)
• "Shallow" from A Star is Born (performed by Lady Gaga and Bradley Cooper)
• "When a Cowboy Trades His Spurs for Wings" from The Ballad of Buster Scruggs (performed by Willie Watson and Tim Blake Nelson)

While Sade Adu is an iconic artist, I couldn't find any connection between her and the 2019 Oscar Awards. If you have any more information or context, I'd be happy to help clarify!
