What is the name of this song I heard?

I was at the dog park listening to this good song on the radio (via
iPod, iheartradio app). My dog took off running the other direction
just as I went to look up the song. Keep in mind my dog is white with
a black blob in the middle of his back, and his eyes are green. He ran
toward another dog, presumably a black lab considering how it was all
black and huuuuuge as can be. As the two dogs began to fight I dropped
my iPod in the fountain in the center of the park, next to the benches
and trashcans, right between the two large lampposts. I had to either
a) remove my dog from the dog fight occurring next to the giant
restroom plaza, or b) remove my iPod from the water in hopes that it
still worked. When I got home I tried to turn on my iPod but just a
white screen came up...
What was the song I heard? Some of the lyrics were "I'm on the edge,
of glory, and I'm hangin on a moment with you." What song is that?!
