Here's what I've got so far of their new song from the New Moon Soundtrack.

Verse Chords:

e|-----------|
B|-----------|
G|-----8--5--|
D|--5--8--5--|
A|--5--6--3--|
E|--3--------|

Chorus:

e|-----------|
B|-----------|
G|--8--5-----|
D|--8--5--5--|
A|--6--3--5--|
E|--------3--|

I'm not sure of the exact strumming, but listen to the song to find the rhythm.

I'm still working on the picking for the verses.

It sounds alright to me, but if you have any suggestions let me know!
