Okay, this is my first tab, so don't be to harsh.
I figured out the intro by watching them play live.
Still in the process of tabbing the rest, but this should give you a good idea of what 
are doing.
I'm sure this is at least 98.9% correct.

Artist: Japandroids
Song: Young Hearts Spark Fire
Tuning: Drop D
|e|
|B|
|G|
|D|
|A|
|D|

Okay, so this is how the intro goes like this. There is a lot of barring:

e|-55-5~-5--5|-000~-0000~--55~-|
B|-88-8~-8/77|-888~-7777~--57~-|
G|-77-7~-7--7|-777~-7777~--77~-|
D|-55-5~-5--5|-077~-0000~--00~-|
A|-55-5~-5--5|-077~------------|
D|-55-5~-5--5|-077~------------|

Then after the songs starts to build-up,
Play the intro like that,
but softly strum the chords you end on in between,
while hitting the chord rhythm in the intro hard. I believe these are the chords in the 
and chorus,
but i'm not finished yet. If you having anything to add,
questions,comments, etc., contact me at jeremiah_hutchison@live.com

Also, here is a simplified version for standard tuning if you need it:

Basically replace the 555785 and the 777780
 bar chords with the G chord below.
Replace the 555775 and the 0775 bar chords with the
D.

e|-5--0--|
B|-0--3--|
G|-0--2--|
D|-0--0--|
A|-2--X--|
E|-3--X--|
