Having an album spend 300 weeks on the Billboard 200 chart is a no easy feat, but for Eminem, he's now been able to accomplish it three separate times. The accomplishment is a first for any artist, according to Forbes.

Earlier this week, Eminem's 2010 album, Recovery, landed at No. 160 on the Billboard chart, making it the 300th week the album has been on the chart. This is the third time an Em album has done this, following Curtain Call: The Hits' 363 weeks on the chart and The Eminem Show's 342 weeks.

While the Detroit rapper hasn't released an album since 2013's The Marshall Mathers LP 2, it appears he's gearing up for a new project. On Oct. 25, the rapper's manager, Paul Rosenberg, posted a photo of himself holding up Yelawolf's Trial by Fire CD. In the background, a fake ad for a product called Revival can be seen.

The ad features Eminem's signature backwards "E" and link for a website that takes you to a page full of references to songs like "I Need a Doctor" and "Lose Yourself."

The rapper will also be appearing as the musical guest on a Nov. 18 episode of Saturday Night Live. Musical guests on the show usually perform two songs, and seeing as the episode airs one day after the usual release day for music (Friday), it appears Em could be dropping an album this month.

In other Slim Shady news, the rapper recently revealed a new line of "Stan" merchandise. A post on the Eminem site features a picture for a hat with "STAN" embroidered on it. No word on when the hat will be available.
