Justin Bieber's new song "What Do You Mean" will be released in 30 days -- on Aug. 28 to be exact -- and he's wasting no time promoting it.

On Wednesday, the 21-year-old singer told Ryan Seacrest on his radio program all about the new up-tempo jam and what he means by that questioning title.

"Well, girls are often just flip-floppy," Bieber explained. "They say something and they mean something else. So … what do you mean? I don't really know, that's why I'm asking."

Bieber also talked about his upcoming album -- his first in three years -- and described the tone as "really uplifting, clear, poppy, but cool."

Need proof? Look no further than his collaboration with Skrillex and Diplo -- "Where Are U Now" -- to get a feel.

"The sounds are super expensive. Skrillex is a genius. He's super futuristic and I just love his sound," Bieber explained. "So to be able to incorporate that sound with what I'm doing has been super cool because it's new and fresh. I feel like no one has done it before."

But all the hard work on his new album has apparently taken a toll on Bieber emotionally. "I get in my head a lot and I get kind of depressed because I want it to work so badly," he shared. "I want people to love it. I want to inspire people. Sometimes I wonder, 'Is this good enough? Is this the direction I want to go?' I had kind of a rough week last week. I get in my head, and I don't want to get out of bed sometimes."

In spite of the rough times, Bieber manages to inspire others, including his adorable half-siblings, Jazmyn and Jaxon. Check out how they sang "Baby" in the video below.
