I shall try the above two, but I still "believe" I need a song entitled just that.
This is a helpful resource for both you and I:
Search: believe lyrics in songs | LyricsMode.com
I've only heard of maybe two or three songs solely titled "Believe", and two of them came after 2007, so no dice.
If you have an inkling of any of the songs found in the list above, and think I might find it worthy, please shout it to me. I don't nearly have to time to listen to 100+ songs called "Believe" just to find one that fits, but with your help, I may only need to listen to 10.
Thank you for your assistance.
