1946: Valerie Simpson is Born.

Today in history, we celebrate the birthday of singer and songwriter, and one half of the dynamic duo Ashford & Simpson, Valerie Simpson. Simpson, along with her husband Nickolas Ashford co-wrote numerous soul hits before beginning their successful performing career in the early 1970s. They wrote for fellow singers like Ray Charles, Marvin Gaye, and Tammi Terrell, creating Motown hits like, “Ain’t No Mountain High Enough.”

Four days before Simpson’s birthday, her husband and writing partner died from throat cancer at the age of 70. Shortly after his death, SFGate spoke with Simpson at her New York home.

“It's just one step at a time," she said. "There's no getting around it. Some days are better than other days. I have a great network of family and friends who lift me up when I just want to go lay down. It's something I didn't expect - to be in this position. Nothing prepares you for it. It's a hard thing to go through."

1997:  Coolio Releases My Soul.

On this day, Compton rapper Coolio released his third album,  My Soul. The first single from the album, “See U When U Get There,” peaked at No. 12 on the Hot 100 and was an international success. The album, which was his last for Tommy Boy, was a minor success in comparison to his previous albums and saw production from  Romeo, Vic C., Bryan "Wino" Dobbs and DJ I-Roc.

1997: Mariah Carey Drops "Honey."

Mariah Carey also released new music on this day with her first single “Honey,” from her sixth album Butterfly. The single became a quick success being Carey's twelfth No. 1 single on the Billboard Hot 100. Remember the sexy video with Carey strutting her revealing outfits, exposed cleavage, and sexual content? Freshly separated from her then-husband, music mogul Tommy Mottola, Mariah introduced the world to a new sexy look along with her new tune.

“Mariah is a diva and anything that divas do, it transcends," Stevie J told Billboard. "Since I and Puff were the hottest producers in hip-hop at the time, doing a collaboration with someone like Mariah Carey, it was bound to blow because everyone knows she’s a helluva vocalist. If she gets on some hip-hop tracks and writes it the right way, it’s gonna be a win-win. So, I had no doubt in my mind she was gonna fly on the hip-hop side. She’s like one of the greatest of all time, and I’m just blessed to have work with her.”

2001: Petey Pablo Represent For North Carolina With "Raise Up."

Petey Pablo put North Carolina on the map when he dropped his debut single “Raise Up.” This summertime hit, produced by Timbaland, reached No. 25 on the Billboard Hot 100.

 “I remember riding down the highway coming from New York to Washington, D.C. playing the instrumental over and over again," Pablo recalled to Billboard. "Then it seemed like a helicopter was following me all the way from Baltimore to Washington, D.C., and I just kept thinking, like, 'North Carolina, come and raise up, take your shirt off, twist it ‘round your hand,' like this helicopter that kept flying over my head. It started as a joke that turned to, 'Wait a minute, that actually sounds good.'"

2003: YoungbloodZ are Drankin Patnaz

2003: Nappy Roots Drop Wooden Leather

Another southern rap group, Nappy Roots, released their second album Wooden Leather on this day.

“Wooden Leather” resembles a lot of things that you come across in American culture," Skinny DeVille told Billboard. "The 'wood' is the structure. You can look at 'leather' as success. If you take care of them both, they will last forever —they both represent quality."

In a Q&A with Seventeen magazine, Solange talks about her journey making the album, “Truly a journey, this was like traveling through the past, present and future of my emotions.
