G-Unit's Tony Yayo recently dropped a new mixtape, titled Gunpowder Guru, a prequel to his upcoming official album.

But, instead of dropping it for free on ThisIs50.com, as most members of G-Unit do, he's making it available for sale at many digital retailers.

In a recent interview with MTV's Mixtape Daily, Yayo said he was inspired by how 50 Cent has been able to cash in on merch, so he's selling the upcoming tape.

"It's [coming out] now, available on Amazon, iTunes and all these other places -- we're rushing to put it out because of the reaction I got to my new video 'Bullets Whistle.' Shout-out to ThisIs50.com. Gunpowder Guru coming out in the next 48 hours," Yayo told MTV.

"Sometimes I be in the studio -- I watch movies, read books and I just zone. I think I got [the title] from a movie, Gunpowder Guru," he explained. "I liked the way it sound. I went with it. It's a real dark mixtape. A lot of it, the production was done by my man Doe Pesci. We decided we give a lot of music away for free. What would 50 do in a position right now? 50 would sell his mixtapes on iTunes. It's all about the Internet now."

Gunpowder Guru consists of 10 brand new tracks from the G-Unit soldier, which are all street-inspired tracks. No soft stuff here.

"I got a joint called 'Murder,' then 'Southside' where I'm shouting out cats like [DJs] Grand Master Vick and Doggtime," Yayo tells MTV. "I got a joint with my artist Louis Castro. The next joint I'm gonna come with is 'Back Against the Wall.' It's a dark vibe. When I seen 50 did the War Angel, it was dark. I took the same vibe."

It is out now. It's available now for $7.99 on Amazon.com, and iTunes.

The Unit is gearing up for an overseas tour later this month, which will run through April. Then, 50 will film two movies before the crew tours in the U.S. in June. After that, Yayo says new albums will be coming.

The albums (from Yayo and Lloyd Banks), however, will be released independently, since they're no longer signed to Interscope Records.
