Rome might not have been built in a day, but Fetty Wap's newest EP sure was.

For My Fans, the five-track collection he dropped on Monday (Nov. 30), was apparently put together in the span of just half a day.

Fetty told Entertainment Weekly that he basically woke up Monday morning and decided to be productive AF, called his manager and was like "Hey, what's up, hello," recorded the songs at his house and dropped the EP, all in less than 12 hours time. Yep.

"I’m indebted to my fans," he explained to EW. (Indeed, the title and NSFW lyrics of the new offering echo that sentiment, as he intros with "I hope you guys f--king like this.")

"The entire EP was recorded in my studio on Nov. 30. I woke up and I called my manager like, ‘I think Im going to drop something,'" the "Trap Queen" rapper-singer, whose IRL name is Willie Maxwell II, explained.

"I called my engineer and I was like, ‘Let’s go to the studio,’ and it’s like 10:30 in the morning and he hadn’t even brushed his teeth. But we started recording at 1 p.m. and finished at 3:30 p.m. We dropped it at, what, like 9 p.m.? I promised my fans so I had to do it."

According to Fetty Wap, there's no telling when his next set of new tunes will come down -- "I just [record] when I get into that mood ... that Fetty Wap mode," he told EW -- but if For My Fans is any indication, it won't take him long to pull the next set together at all.

BTW, Spotify just announced that "Trap Queen," Fetty's break-through single, was 2015's most-streamed song of the year.
