Secular Music: God Inspired?

It's been said that Rock and Metal are the Devil's music. I could give a really good reason why it is not but I'll save that for later.
What I'm thinking is whether or not music of all genres can be God inspired. My answer is an emphatic YES.
One of my favorite songs all time is "Fireflies" by Owl City. Owl City's music is, unarguably secular in most cases, including this one. But Adam Young (Owl City's solitary member) is, in fact, a Christian. He lets God in and we see the returns. While a non christian can enjoy the song, I notice as a Christian the the song, especially the chorus, sounds very God inspired. When I listen to the song, I listen not only to the word, but also to the instrumental work. Fireflies is a gem. Not all of songs like this are God Inspired, some are just what I call "Musical Genius."  A good example of this is R.E.M's "Shiny Happy People"

Anyway, I got my life to live.
