This song isn't too complicated to play, but it's so heartfelt and wonderful :)
I think the feeling is more important than the actual accuracy of your picking 
pattern in this song.
However, you can listen to the song to pick it up easily, or you can incorporate 
your own style, and it will still sound good.
I've played this along with the album, and it all sounded right to me.
