Matthew West - My Own Little World chords

This song has a 4/4 time signature, in the key of E.  What I call an "E9" is a barre
chord on the ninth fret, as opposed to an E1, which is the standard open chord.  The A2 is
a normal A played with only the pinky and ring fingers.  There are three chord
progressions: one for the introduction and verses, another for an instrumental section, 
and a third
for the chorus.  There is a tag at the end of the second chorus, and some changes at the
end.  If you have any questions, post them below and I shall try to answer.  I hope
that this song is a blessing to you!
