Ain't no party like a PopCrush party cause a PopCrush party don't stop! How can you have a festival with today's most popular artists without a rapper? It's just not right!

The lineup of rappers to chose from for the Ultimate PopCrush Music Festival of 2013 are some of today's biggest rappers. Rhyme slingers like Jay-Z and Kanye West have entire catalogs of hits in addition to their joint album 'Watch the Throne' with tracks like 'Otis' and 'N---as in Paris.' Plus, with Yeezy on the stage means anything can happen.

Speaking of legends, Eminem is fixing to make his triumphant comeback with his eighth studio album that will, with no doubt, be as ground-breaking as the seven before it. Performing to thousands of people is a regular occurance for Slim Shady so it's no wonder his larger-than-life personality rocks a crowd like the best of them.

Then there's the Young Money clique -- how could you not want to see one of their ginormous names perform? Nicki Minaj, Drake and Lil Wayne all know how to rock a crowd -- so of course you'd want to be one of the lucky fans to see them, right?

A$AP Rocky had one of the biggest hip-hop releases this year with 'LONG.LIVE.A$AP,' plus he's easy on the eyes. After all, he be that pretty motha f---a. And how could we talk about hip-hop in 2013 without mentioning 2 Chainz? The guy had more features on albums this year than any other rapper in the game. He also released a little album called 'Based on a T.R.U. Story,' which has sold over a half a million copies.

Then there's Macklemore and Kendrick Lamar -- two guys who have had probably the most success of any other rapper in the game this year. Macklemore and partner Ryan Lewis shot to the top of the charts with their hit 'Thrift Shop,' but did so without the help of a major label. Kendrick Lamar's second studio album 'good kid, m.A.A.d city,' was one of the most critically acclaimed releases of the year and has sold close to 900,000 copies to date. You gotta catch these guys live while they're hot!

And how could we forget B.o.B? The guy plays the guitar so get ready for some tasty licks when you see him live! Plus, you never know what guests may show up. Hayley Williams of Paramore, Bruno Mars and more!
