Fluttershy Music Puzzle

This was a little something I decided to do on my father's birthday. He used to play a cover of this song with his band. It's a great song that's been performed by multiple artists— can you name it?

Pictures used

I don't want to name all of the pictures or it might give it away, so all appropriate credits to artists and pictures are linked.
