DJ Funkmaster Flex is famous for party-starting mixes, his old school car collection and his infamous radio rants; oh lord his radio rants.

In the past, the New York native has used his platform on Hot 97 to launch attacks on 2Pac, R. Kelly and Dame Dash, and then on Thursday night the Kingpin threw stinging shots at Jay Z and his Life + Times website.

"I don't care about your website, your website's trash. You can't move with me in this digital space," Flex said yesterday on-air. "Maybe if y'all copied everything I was doing with the app, that app would've did better, it would've crashed the day your album dropped."

(DJ Funkmaster Flex's rant begins at the 10:30 mark.)

The veteran disc jock also went on to offer a vague challenge to Hov, though he never mentioned his name directly. "I let you live in this town, don't think I can't ruin you. Because that's a nice feather in my cap if I ruin you. Today we're bumping heads; your site's trash," he growled.

So where did the drama start?

According to Flex, he began to feel slighted after an interview with Jigga's Life + Times a few years ago. During the interview, the site asked him about his digital endeavors, particularly his In Flex We Trust website and his Funkmaster Flex phone app. Funk believes that Hov, through an L+T reporter, swiped the idea for Flex's phone app and used it to launch Jay-Z's 2013 album Magna Carta... Holy Grail through Hov's own his Samsung phone app.

"They do this interview after I drop my app. Asking me a lot of key questions about apps. Building apps; how, why, how'd you launch it? But all of that didn't get put in the story, though. But a lot of that information got put into that new Jay Z app," he accused.

That was then, but Flex says what set him off yesterday was a second interview request from Life + Times, centered around the DJ's involvement in the latest Dipset reunion. Dipset, of course, once had a vicious rap feud with Jay Z. Flex went on to accuse Jay's 40/40 Club of prohibiting him to play Dipset's music in years past. Dipset leader, Cam'ron made the same accusation in an interview with MTV News in 2013.

“I think he has more of an attitude with us than we have with him. We had our moment back and forth, but I’m kinda over it. Like, if you go to the 40/40 Club, you’re not allowed to play Diplomat music,” Cam told us then.

At the top of the year, Flex, hosted a Dipset reunion freestyle on his radio show and premiered a new song from the group. He's now irked that Hov's site would inquire at his involvement with the group and alludes that their inquires don't come from a genuinely journalistic place.

"Don't play with me man, don't play with me," Flex barked. "I'm a different animal, I show respect, I give respect, I'm neutral. I didn't take no sides in that situation. Play me like I'm stupid, you're going to see a different dude firing off on you. On you."
