Ok this song is sweet
here's the bass riff for the intro and pretty much the whole song, he(?) just repeats it.

~   this little thing means you hold the note for longer, but you really need to listen 
the song to get the feel for it

G---------------------------------------------|
D---------7--------------5--5h7---------------|
A-------7----5~---5--5h7----------------------|
E-5~--5---------------------------------------|

G---------------------------------------------|
D---------7--------------5--5h7---------------|
A-------7----5~---5--5h7----------------------|
E-5~--5---------------------------------------|

at some parts of the song it almost sounds like he simplifies it....

G---------------------------------------------|
D-------7--------------5--5h7-----------------|
A---------5~~---5-5h7-------------------------|
E-5~~-----------------------------------------|


then about three minutes in it's just...

G---------------------------------------------|
D---------------------------------------------|
A---------------------------------------------|
E--------5----5--------------5----5-----------|

then it goes back to the main riff

anyway.....cool song

i heard it on the Garden State soundtrack and i noticed the bass part was rockin'
so there you have it

any problems just......get over it
