Miley Cyrus isn’t exactly known as a paragon of hip- hop music, yet “We Can’t Stop”—one of her most iconic songs—was crafted by one of the genre’s top up-and-comers, Mike Will Made It. Born Michael Len Williams II, the 26-year-old rapper-producer has a knack for working a diverse cast of musicians. In addition to his eight songs on Cyrus’ Bangerz, he’s had a hand it hits by acts from Kanye West to Rihanna to Lil Wayne to Mariah Carey. “When I do music, I don’t think about urban music, pop or country,” Williams told FORBES. “I just think about a good song.” That all-encompassing approach is part of the reason Williams has been selected as a member of our Hip-Hop Cash Princes Class of 2015. The list, which we first launched last year, seeks to highlight the rappers and producers most likely to make our flagship Hip-Hop Cash Kings list one day. Full coverage: Hip-Hop Cash Princes 2015 This year’s list was selected by a panel of expert judges including Cash Princes alum Tyga, Cash Kings alum DJ Khaled, Hot 97 Morning Show host Peter Rosenberg, FORBES staff writer Natalie Robehmed and yours truly. Any hip-hop act under age 30 as of March 31st, 2015 is eligible for the list, as long as he or she hasn’t appeared on a previous Cash Kings or Princes list. The Class of 2015 is made up mostly of rappers, though three who are primarily producers— Williams, Hit-Boy and DJ Mustard—make the cut as well. The latter owes much of his success to a symbiotic relationship with West Coast rapper YG, another Cash Prince. It’s the sort of partnership that can help both sides graduate to Cash Kings levels, as DJ Khaled can attest. “I know the power of a great team,” says Khaled, who earned $7 million last year thanks in part to Rick Ross, a fellow Cash King who has appeared on all of his albums. “Khaled-Ross is a great team, Snoop and Dre is a great team, Puff and Biggie is a great team. I love to see artist and DJs and producers embrace each other and create a movement and support each other’s movements. All this positive energy turns in to success.” Working with a wide range of producers and writers can also have its merits, as many on this list—such as Iggy Azalea— have found. Though the Australian import’s claim that she’s “the realest” has been called into question, there’s no doubting her commercial success: hit single “Fancy” moved 4 million units in the U.S. alone, part of the reason that Azalea has been averaging over $75,000 per stop on the road by Pollstar’s count. Others are disrupting traditional models—take Nipsey Hussle. The indie rapper made $100,000 in a day by selling 1,000 copies of his Crenshaw mixtape for $100 apiece through a pop- up store in his native Los Angeles; Jay Z bought 100 copies. For his next act, Hussle, 29, aims to sell 100 copies of new album Mailbox Money for $1,000 each. “I want to put my cash register in the part of the process that can’t go digital,” Hussle told FORBES, noting that he’s made over $60,000 so far from limited editions that come with keepsakes and fan experiences. Much like the Cash Kings list—which has prompted lyrical callouts in songs by the vast majority of hip-hop’s biggest names, perhaps most notably “ I Get Money (The Forbes 1-2-3 Remix)” by Jay Z, Diddy and 50 Cent—inclusion on the list is a major mark of pride for many of the honorees. “I heard you say we’re Cash Princes,” said Quavious “Quavo” Marshall, one-third of Class of 2015 act Migos, in an interview in Austin earlier this month. “I like that.”
