Probably a long shot, but maybe the song Naturally by Selena Gomez and the Scene.
You don't mean the Pokemon themesong do you?
It made me think of this song https://www.youtube.com/watch?v=Jv94SkcJAm4 by Wax, just in the way the chorus is structured and how it sounds. It also reminded me a little of 15 Dreams by New Politics: https://www.youtube.com/watch?v=bxZQ_Gc21SY. Maybe the line "I'm just man living in a machine" reminded me of the destiny line.
I thought I might be thinking of the Pokemon song too, but that's not it. I'll try these other mentiond
The song has kind of a Smash Mouth feel to me, and their song Stay Home from the Shreck soundtrack starts with "I believe in self-assertion, Destiny or slight diversion.."
This signature says something else when you aren't looking at it.
https://www.youtube.com/watch?v=YYmrPn1CnzY This song (from the Lorax) reminds me of a pop song or something I've heard. It's specifically the "I'm just doing what comes naturally" and "I'm just following my destiny." Maybe it's the destiny line? I feel like I've heard "You know it's my destiny!" to the same tune. Or it may just be the tune I've heard somewhere. Help
