:: Note ::
  In some of my tabs, the chords that are in parentheses are chords that are optionnal. 
For example, in 'Baby U!', the chords stay the same within the intro, but for an 
accoustic cover of the song, one can play the chords of the song as how one feels.
  And so, the chords I put in the outro is an option, what I would play normally, but 
you can chose whatever you like! (But don't push it too much...)

Have fun~
