So, I owe, From Living Things.
It's a very easy song, but so sweet to listen to (i can't get bored of it :D),
ideal for begginers, and funny for intermediates players.
I think my tab is almost the same version as the song.
I thought chords are better than power chords here, 
in acoordance with the harmony of the song.
Enjoy !

Intro
    G     C
|-333-3-xx-xxx-|
|-222-2-33-333-|
|-000-0-22-222-|
|-000-0-00-000-|
|-000-0-11-111-|
|-333-3-00-000-|

Chorus
|x---3--5-3-0-3-x|
|3---3----------3|
|2---2----------2|
|0---0----------0|
|1---0----------1|
|0---3----------0|

This is not absolutly needed but, when he says "all we need is love", 
you can play a A between G and C:

   G  A  C
|-333-x-xx-xxx-|
|-222-0-33-333-|
|-000-2-22-222-|
|-000-2-00-000-|
|-000-2-11-111-|
|-333-0-00-000-|

If you're begginer, it will seem to be a little fast,
but if you practice a bit, you'll see it's easy !
