Eminem investing in music annotation company

Eminem has joined fellow rappers Nas and Pharrell Williams as an investor in music annotation company Genius.

The company will serve as the official annotation hub for the star's new music and the lyrics engine for Eminem.com. It will also house the annotations and lyrics for all of Eminem's Shady Records online properties, according to Billboard.com.

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

"Genius provides an avenue for fans to dig deeper into their favourite songs, but more importantly, it gives artists a way to communicate their artistic intent directly to those fans," Eminem's manager Paul Rosenberg adds. "For an artist like Eminem, the intricacies and nuances in his lyrics are very layered and his art is a perfect fit for this type of tool. We're excited about what this partnership brings for both sides."

The company was founded in 2009.
