A friend of mine introduced me to this awesome song so here's a quick tab on it!

Here's me trying to explain the rough pattern and then just follow the tempo: 
For bar chords with bass on 5th string, its (Bass + second string, bass, 3rd string, 2nd string).
For bar chords with bass on 6th string, its (Bass + third string, bass, 4th string, 3rd string).

Sorry i'm not good at chord names, so here's how i play them!
