Hey! So I'm covering Stay with Me by Sam Smith and am totally stuck with strumming. The song has such a great mood, but I just can't seem to get it down. I found this cover (http://www.youtube.com/watch?v=TyCwu3h3U-8) and love her take on the song, but can't quite figure out her strumming either. Any help or suggestions? It's a pretty simple song! Just Am7, C, F, and G.

This is the original song: http://www.youtube.com/watch?v=pB-5XG-DbAA

Thanks so much!
