Intro:
No bass till 0:06

G|------------|
D|/77777777777|
A|------------|
E|------------|

then at 0:15 it switches too (I'm kinda iffy about this bit, might not be right)

g|-----------|
D|7755-------|
A|----88 X 2-|
E|-----------|

Verse: (Those are 10s and 12s)

G|--------------|
D|77101033121212|
A|--------------|  X 9
E|--------------|

Iffy bit again:
g|-----------|
D|7755-------|
A|----88 X 3-|
E|-----------|

then it randomly goes:

G|----------------|
D|----------------|
A|7878787878787878|  X 1
E|----------------|

Then back to iffy bit:
g|-----------|
D|7755-------|
A|----88 X 2-|
E|-----------|

then when she goes "No one can take it from me" it changes too:

G|------------|
D|777555333222|
A|------------| X 1
E|------------|

Back to verse, than repeat everything after that.

Nothing new till the bridge at 1:55 (cause it's miiiiiiiiiine...)
which goes like this:

G|-----------------------------|
D|-------------------------7-5-|
A|7-77-77-77787878787878-7-----|
E|-----------------------------|

Then play the verse bit during the guitar solo

Then it's a sick drum beat with no bass till 2:34
which goes like this:

G|-----------------------------------------------------------------|
D|\77-777-777-777-777-777-777-777-777-777-777-777-777-777-777------|
A|-----------------------------------------------------------  X 1-|
E|-----------------------------------------------------------------|

then back to:

g|-------|
D|7755---|
A|----88-| for a long time
E|-------|

then end with:

G|------------|
D|777555333222|
A|------------| X 1
E|------------|

The end!
This might not be 100% acurate, but I think it's good enough.
