Legendary DJ Funkmaster Flex returns to the mixtape game with one helluva project titled 'Who You Mad At? Me or Yourself?'

This colossal mixtape from the Hot 97 DJ is reminiscent of his mid-'90s compilation series '60 Minutes of Funk.' Almost every rapper in the music industry is featured in the collection.

The tape is set up with two different playlists -- Camaro and Mustang. Altogether, there are 53 songs featuring both upstart rappers and veteran rhyme-slingers in the game. The collection also boasts production assists from Swizz Beatz, DJ Mustard, Harry Fraud, The Runners, Hit-Boy, Statik Selektah, araabMUZIK, Juicy J, Ted Smooth, Jahlil Beats, Young Chop and Beat Billionaire.

The project is available on the DJ Funkmaster Flex music app at both iTunes and Google Play -- a first for mixtape releases.

Much of the music on 'Who You Mad At?' are of the boom-bap variety with unique samples and gritty wordplay from the rappers.

One of the many standout tracks is 'Love to a Diplomat,' a collaborative joint from Cam'ron and Lil Wayne. The song takes you back to the days when Killa Cam was spitting catchy punchlines with the Dipset crew.

Another interesting song is from Childish Gambino who raps clever lines over a lush soul-sampled groove on 'Think of Me.' J. Cole shines, spitting braggadocios rhymes on 'Maine on Fire.' Elsewhere, Joell Ortiz takes it back to the '90s on the head-nodding banger 'Roll Deep.' The Slaughterhouse rapper is at his rawest here over booming drum rolls and clever soundbites.

A few up-and-comers get plenty of shine here as well. Action Bronson takes us on a road trip to Queens on the throwback-sounding 'Live From Kissena Blvd.' Brooklyn rhymer Joey Bada$$ spits acidic flows on the sinister 'Hot Box.'

A song that will probably raise a few eyebrows comes courtesy of Uncle Murda on 'Do Sumthin.' The Brooklyn rapper accuses Suge Knight for the murder of BK's most beloved emcee Notorious B.I.G. and vows to get his revenge. "I make Brooklyn look good homie, and I'm patiently waiting to kill Suge, homie," he raps.

Funkmaster Flex's 'Who You Mad At?' pulls no punches and is full of certified street bangers that will keep you entertained for hours.
