Rap Song--Birrrrdman!

I heard the end of a rap song on the radio and have no idea who did it. This was a few years ago (maybe two). The very end of the song ends with the phrase "Birrrrrdman" just like in the cartoon.

You can hear how Birdman says it at the end of the opening credits for the cartoon:

I have listened to samples on Amazon from the artist named Birdman but I don't think it's any of his songs. Of course, I am listening to the middle of the song so I can't hear the end. But his style seems different and the lyrics to this song were kind of comic-booky or about superheroics (rap-type boasting style that is). And the music occasionally used the sound effects ofrom Saturday morning TV superhero cartoons as I recall.

I know that's not much to go on, but it's all I got. But if you ever heard the song, you wouldn't forget the "Birrrrrdman" at the very end... it's very funny!

Thanks!
