Mac Miller Is Wiz Khalifa's Hottest Breakthrough MC

'Mac gotta win that for sure,' Wiz tells 'RapFix Live' of fellow Pittsburgh rapper.

[artist id="2427571"]Wiz Khalifa[/artist] knows a thing or two about breaking through to the mainstream. In 2010, the Taylor Gang general was voted by fans as MTV News' Hottest Breakthrough MC of 2010. He beat out J. Cole and Nicki Minaj and went on to release his debut album, Rolling Papers, then had rap fans across the word singing his hits "Black and Yellow" and "On My Level."

When it comes to the 2011 Hottest Breakthrough MC competition, Wiz is in support of all 10 of the nominees, but he does have his favorite. In a pool that includes A$AP Rocky, Future, Freddie Gibbs, French Montana, Kendrick Lamar, Machine Gun Kelly, Meek Mill, Lil Twist and Roscoe Dash, Khalifa is picking his Rostrum Records labelmate and fellow Pittsburgh MC to take it all: [artist id="3864891"]Mac Miller[/artist].

"Those are all great names, and I've met all of those kids — well, some of them aren't kids," Wiz told "RapFix Live" on Wednesday. "But I gotta go with the hometown, Mac."

Mac Miller, like Khalifa, hails from Pittsburgh. He made a name for himself with his 2010 mixtape K.I.D.S. and its 2011 follow-up, Best Day Ever. In 2011, Mac toured the country, sold out shows and saw his "Donald Trump" single chart on the Billboard Hot 100. Miller pulled off his biggest feat, however, when his independent debut, Blue Slide Park, became the #1 album in the country.

"Mac gotta win that for sure, 'cause he did the numbers, he did the tour, he got the fans, he's got the merch," Khalifa said. "All those guys that you named definitely had successful and fun years, but I gotta go with my hometown, Malcolm."

Each day, we'll spotlight a new Hottest Breakthrough MC before concluding Tuesday when the polls close at 11:59 p.m. ET. The 2011 Hottest Breakthrough MC will be revealed during Wednesday's "RapFix Live," during which the winner will appear as our in-studio guest. There will also be a special announcement about MTV News' upcoming Hottest MCs in the Game list and debate.

To be considered a Hottest Breakthrough MC, an artist cannot have released a major-label full-length album. Finalists from 2010's Hottest Breakthrough MCs poll will not be eligible for 2011 consideration, so unfortunately, Diggy Simmons and Travis Porter won't be part of this conversation.
