I like to play the chords like this in the intro and chorus:
   G    C     Em     D
E|-3----0-----0------2---------------------------------
B|-3----1-----0------3---------------------------------
G|-0----0-----0------2---------------------------------
D|-0----2-----2------0---------------------------------
A|-2----3-----2------0---------------------------------
E|-3----3-----0----------------------------------------


and like this in the verses:
   G    C     Em     D
E|-3----3-----3------3---------------------------------
B|-3----3-----3------3---------------------------------
G|-0----0-----0------2---------------------------------
D|-0----2-----2------0---------------------------------
A|-2----3-----2------0---------------------------------
E|-3----3-----0----------------------------------------

But again, play how YOU like it.

Intro: G
then go: G C Em D G

The Em and D are played twice as fast as the G and C 
(so they're one bar together,
while the other ones are one bar apart.
You'll get it if you listen to the song.
Listen to the bassline for the rhythm when this part 
comes along again.

G         D        C
Butterfly belly aches
C         D          G
Keep me up night and day
G     D       C
Radiate sunshine
C        D          G
And make it reverberate
G               C
Looking for a reason
Em      D     G
Nothing but scraps of food
G                 C
In the spirit of the season
Em      D        G
All I want is to unwrap you

G
I can't get enough of your love [x4]

G C Em D G

G      D        C
Get up on the table
C         D       G
And see if that works for us
G      D      C
Everything changes
C         D          G
Into nothing too outrageous

G
I can't get enough of your love
C
(Never get enough)
Em         D           G
I can't get enough of your love
G
I can't get enough of your love
C
(Never get enough)
Em         D           G
I can't get enough of your love

C
Come on, come on, come on, come on, come on
G
See it through your window
F
Come on, come on, come on, come on
Em
Tomorrow's miles away
C
And the radio will play your song
G
It's been traveling forever
D
Come on, come on with me today
D
And let it lead the way

Solo: Am C G Am C D

G        D        C

And make it reverberate
