I was listening to this sweet song and fooling around with my guitar and
seemingly found a few chords that sound great imo arpeggiated with the song

Standard tuning:

C  [x32010]
G  [320033]
Am [x02210]
Fm [133211]

I selected to play it as so:
  |C      |G          |Am      |Fm

e------0-------3-----------0-------1----------|
B-------1-------3-3--3------1-------1-1--1----|
G----0---0-------0--0-----2--2-------2--2-----|
D---2--------0-----------2--------3-----------|
A--3--------2-----------0--------3------------|
E----------3--------------------1-------------|

Looped..
Basically what i do is variate the fingerpicking and the style, sometimes alter the 
and pick 2 strings at once to variate and make it sound better or at times play G instead of 
again still sounds good...

Let loose and it'll sound great :)

This might not be spot on but it i think it sounds nice to this song
and is worth a try..
2nd tab ever so don't bother saying i suck, it's a fact, but if you like it
let me know :)
