Note: b ---> flat
I can't find a better symbol. ^_^;;

This song is in D# major (or Eb major, whatever you want to
call it. Uh, I think I'll use Eb). This song is mostly
strumming, so here I'll give you mostly chords.

Intro:
Eb Bb Cm Bb Eb Bb Cm Bb (Figure out the timing yourself).

Verse:

in the middle of the chorus, this comes up:
------------------------------8\---------3----------|
----------------------------------------------------|
----------------------------------------------------|
----------------------------------------------------|
----------------------------------------------------|
----------------------------------------------------|
Sun goes down     me wo tojite     Fukinukeru...

-------------------------------8\---3---------------|
----------------------------------------------------|

----------------10/--------------13\----9----4\-1----------|
-----------------------------------------------------------|
-------------------------------------------------------6\--|
-----------------------------------------------------------|
-----------------------------------------------------------|
-----------------------------------------------------------|
Itsudemo kimi no soba ni iru kara douka sono tabi wo akiramenaide

Something like that. The timing is approximate. You can figure it
out yourself.

And then the intro: Same.
Verse: Same.
Chorus: Same but for one thing.

At the end of the second chorus (uh, this counts as a solo, I guess):

And that's it. My first serious (and complete this time) tab.
