Big Sean's Dark Sky Paradise album is filled with upbeat bangers like "Blessings" and "IDFWU," but the Detroit rapper's latest single - the emotional "One Man Can Change The World" - goes in a different direction.

"Never had a song like this be a single," the MC said on Instagram Friday (Jun. 19) upon the video's release. "It’s different than what’s on radio, but I feel it’s needed with all the craziness going on right now."

The song, which features Kanye West and John Legend, is an emotional tribute to Sean's late grandmother Mildred V. Leonard.

"I hope my grandma is looking down smiling on me right now," the Detroit rapper added in his IG post. "The struggles she went through to become a female black captain in World War 2, one of the first female black officers in Detroit, a teacher/counselor, an amazing mom/grandma were too great for this song not to be a single."

In February, Sean shed tears as this song played at a private listening session for the album. That day, he spoke with MTV News about why the single moved him so much.

“I just lost my grandma,” he said. “So, right before she passed, I wrote this song. A major part of the song is about her. She never got a chance to hear it. It’s just an emotional thing."

“It’s just a song that comes straight 100 percent from the heart,” Sean continued. “I hope people can enjoy it. And I really appreciate John Legend and Kanye West being a part of that.”

It looks like Sean Don isn't done with singles from Dark Sky Paradise. "A lot more singles and videos for you coming from the album," he said on IG today. We can't wait to see what else he has in store.
