Joined by numerous Hip-Hop legends, Eminem certainly brought an exciting performance at the launch party of Dr. Dre and Jimmy Iovine's Beats Music streaming service at Los Angeles' Belasco Theater over the weekend.

The Live Playlist event curated a special 90s playlist of throwback performances from Ice Cube ("Today Was a Good Day"), Cypress Hill ("Insane in the Brain"), Pharcyde ("Passin' Me By"), Bone Thugs-N-Harmony ("Thuggish Ruggish Bone"), Nas ("Nas Is Like" / "If I Ruled the World"), Dr. Dre ("California Love"), Black Street ("No Diggy"), and Busta Rhymes ("Put Your Hands Where My Eyes Could See"). Also, Diddy and Ma$e reunited onstage to perform their collaboration, "It's All About the Benjamins."

Beats Music -- a paid, subscription-based streaming service -- was originated from Dr. Dre and Iovine's Beats Electronic, which is best known for its impressive line of headphones. Eminem, who was nominated for the Best Rap Performance category at this year's 56th Annual Grammy Awards, first revealed his public affiliation with the company back in August 2013 with a collaborative commercial during the MTV Video Music Awards announcing his latest album, The Marshall Mathers LP 2.

Slim Shady's manager Paul Rosenberg previously explained of the partnership. "The partnership with Beats is the relationship with Em, Dre and Jimmy from the beginning of time," he said. "That's really where that comes from. When we were discussing who the potential partners were going to be for this record, it was the first time that Beats was able to come in and say, 'Hey, we're the right partner for you, because there's obvious natural synergy, and by the way, we're a really a big company now and we can do this.'"

The Detroit rapper and his long-time collaborator Dr. Dre closed out the show with their hits, including "My Name Is," "Lose Yourself," and "Forget About Dre."

Beats Music's $4 million 30-second Super Bowl advertisement is slated to air on Sunday, Feb. 2.
