Orson - Happiness Tabs

Orson - Happiness

        First of all i think this is a great riff by a band who are 
perceived as "a pop band", well i think this song rocks. Bear with me 
because this is my first tab and if it needs correcting tell me via

standard tuning e b g d a e

there is an intro with a synthetic sound, you can play over it with a
C#minor7

the verse:
    B  C#min7 B   A
|-------4-4-------------|
|---4-4-5-5---4-4-2-2---|
|---4-4-4-4---4-4-2-2---|
|---4-4-6-6---4-4-2-2---|
|-------4-4---2-2-------|
|-----------------------|               

prechorus:
   G5   C#min7
|------4-4-x-4-x-4-4-4-4-x-|
|------5-5-x-5-x-5-5-5-5-x-|
|------4-4-x-4-x-4-4-4-4-x-|
|---2--6-6-x-6-x-6-6-6-6-x-|
|---2--4-4-x-4-x-4-4-4-4-x-|
|----------x---x---------x-|

I can't quite make out the chorus, its very distorted and hard to 
make out when chords actually change.
