Musicians and celebrities are paying tribute to Coolio, the late rap star who was behind one of hip-hop’s greatest hits, and whose own moniker would become shorthand for a good result.

According to reports, Coolio was found dead on the bathroom floor at his friend’s house on Wednesday (Sept. 28). First responders initially suspect that he suffered cardiac arrest, however, at the time of writing, an official cause of death has yet to be determined.

The U.S. artist (real name Artis Leon Ivey Jr.) landed one of the all-time hip-hop standouts with “Gangsta’s Paradise,” a song that which interpolates Stevie Wonder’s 1976 song “Pastime Paradise” and featured in the Michelle Pfeiffer-starring film from 1995, Dangerous Minds.

“Gangsta’s Paradise” was no run-of-the-mill hit. It went supernova, everywhere. In Australia, the single led the national ARIA Chart for an unbroken 13 weeks in 1995 – a streak that stood until Ed Sheeran’s “Shape of You” ruled the survey for 14 straight weeks following its release in 2017.

The enduring nature of the song was confirmed when, in July of this year, “Gangsta’s Paradise” joined YouTube’s one billion views club.

The official music video scooped the best rap video category at the 1995 MTV Video Music Awards, the same year it was crowned the best-selling single on Music‘s year-end Music Hot 100 chart after spending 12 weeks in the top two positions; it logged a total of 62 weeks on the chart, including 3 at No. 1 and 11 weeks at No. 1 on Music‘s hot rap songs tally.

The track, one of Coolio’s six hits on the Music Hot 100 chart, would go on to win the Music Music Award for single of the year, and a Grammy Award for best rap solo performance.

If everything in your life was “coolio” in the 1990s, you were doing just fine.

Tributes are pouring in for Coolio, including messages from the likes of Questlove, Ice Cube and Weird Al Yankovic, who parodied “Gangsta’s Paradise” with “Amish Paradise.”
