Tuning: Drop D (DADGBE)

The first bass (keyboard actually) riff is this:
[----------------------------------------------------------
-----------------------------------------------------------
-5--5---5--5--1--1--------5--5--5---5--1-------------------
--------------------3--1------------------3--1-------------]

And then the guitar and weird keyboard stuff comes in.
The main guitar riff is this (palm mute the 6th string notes)
[---------------------------------------------------------
----------------------------------------------------------
-7-----7-7-----7-----7-7----------------------------------
-7-----7-7-----7-----7-7-----8-----8------3--1------------
-5-----5-5-----5-----5-5-----8-----8------3--1------------
---0-0-----0-0---0-0-----0-0-8-8-8-8------3--1------------]

Play this through the verse and between verses and choruses.
Sometimes there's palm muted open 6th string notes instead
of the D power chords.

The chorus part is this:
[-----------------------------------------------------------
-----------------------------------------------------------
-----7--7-7--------------5--5-5--3-3-3--3-3----------------
-----5--5-5--------------3--3-3--1-1-1--1-1----------------
-----5--5-5--------------3--3-3--1-1-1--1-1----------------
-5-5-5--5-5-6x, then-3-3-3--3-3--1-1-1--1-1----------------]

Lyrics:

Verse 1:
The past few years have been so trying
Between the drugs and the drinking and the touring
And in my eyes I'm stabilized
And all I need is you, someone who understands

Chorus:
I know you now, the shortest yet
And we've just met
I thought that you'd be different, then again
You came off strange but still the same as what I know
I try and try and then I'm alone again

Verse 2:
Now my life's become a challenge
Because my confidence has been decreased profoundly
And in my mind I realize
I'm stuck on a worthless hill, with no one who understands
