Colbie Caillat - Oxygen Tabs

(Intro)
So... basing this off the Oxygen chords tab... I think this is the intro. Im sorta
to have figured this out because this is the first tab i've really done by myself...either
it is probably prone to error consider i am basically a rookie at guitar. however, if 
with more experience feels like listening to the song and correcting this, that'd be
here it is:

CAPO 1

e 2--|2--|2--|3--|3--|3--|5--|5--|5--|3--|3--|3--| (Propably repeat 2x)
B -3-|-3-|-3-|-3-|-3-|-3-|-3-|-3-|-3-|-3-|-3-|-3-|
G --2|--2|---|--2|--2|---|--2|--2|---|--2|--2|--2|
D ---|---|---|---|---|---|---|---|---|---|---|---|
A ---|---|---|---|---|---|---|---|---|---|---|---|
E ---|---|---|---|---|---|---|---|---|---|---|---|

Hopefully this works out and is close enough for an expert to use and figure out the
way... but for now, I like it.
