Psy - Gangnam Style Chords & Tabs

Artist: PSY
Song: Gangnam Style
Tab: Bass (Standard tuning)

After hearing Gangnam style so many times i thought i'd try to enjoy it so I picked up 
my bass and started playing along, i realized there isn't a tab on here yet so...


This is roughly how the bass part sounds
probably not 100% correct but sounds close enough.
G|--------------7-|----------------|
D|----9--9----9---|---9-9-9--7-----|
A|2/-------2\-----|2/----------9-7-|
E|----------------|----------------| X3
[ Tab from: https://www.guitartabs.cc/tabs/p/psy/gangnam_style_btab_ver_2.html ]
G|--------------7-|----------------|
D|----9--9----9---|----------------|
A|2/-------2\-----|7--7--7--9--9--9|
E|----------------|----------------| X1

Or alternatively you can
play it like this:
G|--------------7-|----------------|
D|----9--9--7-9---|----9--9--7-----|
A|2/--------------|2/----------9-7-|
E|----------------|----------------| X3

G|--------------7-|----------------|
D|----9--9--7-9---|----------------|
A|2/--------------|7--7--7--9--9--9|
E|----------------|----------------| X1
