However, the singer refrained from going into detail about what she believes happened.
"I can't share," she said simply.

The haunting track is called "Sometimes It Snows in April" from his 1986 album, Parade.
"Sometimes I wish life was never-ending," Prince sings. "And all good things, they say, never last."
In an eerie coincidence, the song was first recorded on April 21, 1985. Prince died on April 21, 2016.

While "Sometimes It Snows in April" has drawn attention for when Prince died, another song, "Let's Go Crazy," is being talked about for where he spent his final moments.
The singer was found unresponsive in an elevator at his Paisley Park estate in Chanhassen, Minnesota, where medical personnel was unable to revive him. Elevators and death are key themes in "Let's Go Crazy."
"And if the elevator tries to bring you down//Go crazy. Punch a higher floor," Prince belts out on the dance track.
