Buzz so big he could even sell a free mixtape? Drake’s buzz is about to be put to the test commercially.

Before he releases his debut album Thank Me Later, Drake will re-release his popular mixtape, So Far Gone. The album, which will include the hits “Best I Ever Had” and “Successful,” goes to retailers on September 15, according to MTV News. The revamped project will also feature a new song called “Fear,” which will be added to the end of So Far Gone and will serve as the transition from his mixtape to Thank Me Later.

“I did this song that no one has ever heard before, ever,” he told MTV News. “[It’s] a song called ‘Fear.’ I recorded it when I did So Far Gone—the first verse and half of the second verse I had gotten through. But then I just stopped because it was getting eerie. It was getting where I didn’t know if I could [finish it]. And then the other night I had a moment and I finished the song. That’s gonna be the last song on the retail [version of] So Far Gone. And the third verse transitions into Thank Me Later. So the last line of the third verse is gonna be the first line on my album.”

Drake wrapped the video for “Successful” with Trey Songz earlier this week in his hometown of Toronto where he is recovering from a torn ACL.
