Eminem has some of the most iconic songs in hip hop. Now fans can actually buy shares of the rapper's library, getting a piece of all of his royalties.

Two of Eminem's former producers, Jeff and Mark Bass (also known as the Bass Brothers), are selling up to 25 percent of their shares of Slim's earliest songs to Royalty Flow according to the Financial Times.

Royalty Flow is a start-up that hopes to become a marketplace for selling masters (and the money that comes with them) of all sorts of artists.

Right now, the Bass Brothers are offering shares of Eminem's masters from 1999 to 2013. Em hits from that era include "Lose Yourself," "Stan" and "Cleanin' Out My Closet."

How does all of this work? 

Well, when an artist makes a song, they may or may not actually own that song. For instance, Michael Jackson famously owned most of the Beatles' songs. Every time a Beatles' song was played in a commercial or a movie, Michael got paid.

The same is true of Slim's early songs. For a price, anyone can now get a piece of the earnings the Bass Brothers take in from owning Em's early catalog. 

 How much do you have to pay to get in on the action?

According to a Royalty Exchange press release, shares cost $15. But, you have to buy at least 150 shares, which comes to $2,250.

Once Royalty Exchange makes at least $11 million selling shares of stock, its founders plan to take the company public.

If all goes well, investors will make money thanks to streaming and television/film usage deals.

As only the parts of Eminem's catalog that the Bass Brothers own are included in the deal, Eminem himself "is not involved in any deals for the sale of recording royalties and has no connection to this company," according to Royalty Exchange.

The company hopes that the Detroit rapper's catalog will be just the start. It plans to offer fans a chance to invest in the catalogs of other artists in the future.
