Eminem is getting in on the entrepreneurial wave. The 43-year-old rhymer is set to partner with the annotation site and app, Genius.

Formerly known as Rap Genius, the site launched in 2009 as a destination for music fans to get the break down song lyrics, news reports and academic texts. For Em, a lyricist who constantly has fans deciphering his rhymes, the new partnership seems like a match made in heaven.

“Coming up we would always obsess over the lyrics from our favorite MCs. Picking everything apart, trying to get into their heads,” said Em in a statement announcing the partnership. “I still do that today and Genius helps to make it a worldwide conversation. Pretty amazing to me.”

Although it's unclear the amount Eminem will be sending over to Genius, the site will now take over the lyrics section on Eminem.com and take a part in Shady Records' site. Slim will also continue writing personal annotations on his lyrics as well -- in April alone he contributed 42 to the site.

Genius is excited to partner with one of the best as well.

“Any discussion of the greatest rapper of all time has to include Eminem, so working with him and Shady Records is just incredible as a fan,” said Ilan Zechory, Co-Founder and President of Genius in the press release. “With Genius we’re trying to create something like a museum of songs — we want to give all the great ‘behind the music’ stories from Eminem a permanent home for fans to enjoy.”

Em isn't the first artist to embark on the journey with Genius either. Music greats like Nas and Pharrell have also contributed funding to the site.
