芭比之森林公主歌词——Always More
Always More
Ev 'ry body is
born to care
It's some thing we were
meant to share
Not to keep to ourselves all alone
If we make room for
some one new
Does n't mean that there's
less for you
only means that our
.circle has grown
Love knows
Love grows
Bigger than before
In your heart
there's
ALWAYS MORE
It's magic
The more you give it a way
The more love comesback to you
every day
You are my
Tika and
I am your Ro
Always for
ever where
ever we go
so
Love knows
Love grows
Bigger than before
In yourheart
there's
ALWAYS
MORE.
ALWAYS
MORE
