Head First In The River

There's some parts I couldn't really figure out.
If you figure them out, kudos. 
I play it in Drop D. But If you like, you can play it in Standard.
I'm sure you'll know the differences made between the two tunings.

e|--7-------5------/7-------|
B|--8-------7------/7-------|
G|--9-[x16]-6-[x8]-/7-[x8]--|    Intro/Rhythm. 
D|--9-------7------/7-------|
A|--7-------5---------------|
E|--x-------x---------------|

This part I'm not completely sure, but it sounds alright to me.
Played during chorus.
