here's a rough idea of how the song goes
[ Tab from: http://www.guitaretab.com/b/bigbang/308492.html ]
e-----------0--------------------2--------3------------3-------------|
B---------3------------0-------0--------------------3----------------|
G-------0------------2-------2---------4---4-----0-------------------|
D-----2------------0-------1---------2---------0---------------------|
A---3------------2-------2-------------------------------------------|
E--------------3-----------------------------------------------------|
and if you want, use these 5 chords throughout the whole song
