These are a couple of different sections of the song U R So Fucked by Infected Mushroom. 
This is my first tab, and this is a bit of a dubstep/house song so bear with be.


This is that little riff towards the middle/end.
E|-15-14-12-10---------------------------------10-10-15-15-15-12-|
B|-------------12-12-12-10---------------10-12-------------------|
G|-------------------------12-11-9-11-12-------------------------|
D|---------------------------------------------------------------|
A|---------------------------------------------------------------|
E|---------------------------------------------------------------|

then it ends with this
E|-15-14-12-10----------------------------------|
B|-------------12-12-12-10----------------------|
G|-------------------------12-11-11-9-12-11-9---|
D|----------------------------------------------|
A|----------------------------------------------|
E|----------------------------------------------|

These are the power chords used in the beginning

E|-------------------|
B|-------------------|
G|-------------------|
D|----2----5----7----|
A|----2----5----7----|
E|----0----3----5----|

around the middle, the synth switches to this type of chord pattern, still keeping with 
the em, G, A progression.

E|-----7-----7-----7-----7-----3-----3-----5-----5--|
B|-----8-----8-----8-----8-----3-----3-----5-----5--|
G|-----9-----9-----9-----9-----4-----4-----6-----6--|
D|-----9-----9-----9-----9-----5-----5-----7-----7--|
A|--7--7--7--7--7--7--7--7-----5-----5-----7-----7--|
E|-----------------------3--3--3--3--3--5--5--5--5--|
