The song was the first single released from No. 6 Collaborations Project
. The title relates to an EP he released back in 2011 – No 5 Collaborations Project
– and fulfills Sheeran's long-held dream to do something similar again.
Sheeran told Charlamagne Tha God the album initially started with an idea to collaborate on a song with some of the biggest male pop stars, such as Bruno Mars and Justin Bieber. He compared it to 2001's "Lady Marmalade
" which united Christina Aguilera, Pink, Mya and Lil Kim.
"You remember 'Lady Marmalade'? This was such a silly idea," he said. "But I had the idea of doing that and I was like, 'Oh, you could get Bruno, Bieber and me on a record. How fun would that be?'"
Ultimately, the proposed track never came to fruition but Sheeran recorded a series of separate songs instead including "I Don't Care."
