“Detail came to the studio like … He cut the music off — ‘Man I’m about to work with Beyoncé. Can you please do this record man? She like the way you do yo’ songs’ … and she this and that. We were working so much together, he ended up getting me to do it.
He put me in the booth. The song was already pre-wrote. I started doing the little melody — my melody that you can pretty much tell from “Turn on The Lights.”
If you listen to the records these are the same melodies I’ve been doing — “Never End,” “Turn Off The Lights.” If you go back to my mixtapes you hear my melody all over it — so it wasn’t that issue.
It was just, he was working with her, ended up cutting the record first & gave it to her. We had [done] the record about eight months before she put it out.”
He goes on to say that during that time, he made “Good Morning” thinking Beyoncé wasn’t ever going to put “Drunk in Love ” out — but she did and thus “Good Morning” was scrapped.
Still unclear as to whether or not Future wrote anything on “Drunk in Love,” Elliott Wilson points out that both songs feature the line “we be all night” and Future clarifies that everything was written around the same time.
Elliott : “Why aren’t you properly credited for that song and why can’t you just put yours out?”
Future: “I don’t know. You gotta ask them that. I was like ‘Let me put “Good Morning” out since y’all put “Drunk in Love” out.’ [They were] like ‘nah.’”
Elliott: “But you weren’t credited on ‘Drunk In Love’”
Future: “Nope. That’s why they won’t let me put it out *laughs*”
