This is my first song I submit so, maybe there are some errors. But actually it sounds great.

(Piano part)
G
I don't want a lot for Christmas
Bm
There is just one thing I need
C                                  Eb
I don't care about the presents underneath the Christmas tree
G
I just want you for my own
Em
More than you could ever know
C
Make my wish come true
Am                   D            G
Baby all I want for Christmas is you
