T-Pain told MTV News about this collaboration with Lil Wayne: He said: "'Can't Believe It,' I just wanted to simplify things. Basically I got a lot of stuff on my albums that's not that simple. I'm not getting away from the simplicity of things, it's just basically a way to calm things down. Then I put Wayne on it and he keeps murdering tracks I'm sending him. It's just another world, it's unexplainable."
This features T-Pain's trademark Auto-Tune vocals. The Florida rapper told Rolling Stone with a grin: "Auto-Tune's stuck with me. People told me to stop using it, but I would not stop. It works!"
T-Pain explained the song to MTV News. He said: "[The song] is basically a perspective of not settling for what you doing. You can be doing better. Even if you think you're at the peak of your career, you're at the top, it's something else you can be doing. Don't settle into what you been pretty much forced into doing."
T-Pain talked about the video to MTV: "It was all green-screen. I just came up with it, man. I kinda stole some stuff from the last iTunes commercial. I got the same people to direct it. I was like, 'If we can find those people to direct my next video, it will be the best video.' I already knew, just the way I see things. We just did a bunch of takes. Nothing has to be organized. We was like, 'We gonna do it and then see what we got outta that.' It just all came together. It took eight hours. A bunch of takes, six outfits. And the song ain't even four minutes."
