хм...ну не может просто быть такого чтоб ни одной оптимистичной доброй песни...
вот тебе текст одной. помойму вполне теплая и светлая. мне нравится.

HEAL THE WORLD
There's a place in
your heart
and I know that it is love
and this place could
be much
brighter than tomorrow
and if you really try
you'll find there's no need
to cry
in this place you'll feel
there's no hurt or sorrow

There are ways
to get there
if you care enough
for the living
make a little space
a better place...

*Chorus*
Heal the world
make it a better place
for you and for me
and the entire human race
there are people dying
if you care enough
for the living
make a better place
for you and for me

If you want to know why
there's a love that
cannot lie
love is strong
it only cares of
joyful giving
if we try
we shall see
in this bliss
we cannot feel
fear or dread
we stop existing and
start living

Then it feels that always
love's enough for
us growing
so make a better world
make a better world...

*Chorus*

And the dream we were
conceived in
will reveal a joyful face
and the word we
once believed in
will shine again in grace
then why do we keep
strangling life
wound this earth
crucify it's soul
though it's plain to see
this world is heavenly
be God's glow

We could fly so high
let our spirits never die
in my heart
I feel you are all
my brothers
create a world with
no fear
together we cry
happy tears
see the nations turn
their swords
into plowshares

We could really get there
if you cared enough for the living
make a little space
to make a better place...

*Chorus* x 3

There are people dying
if you care enough
for the living
make a better place for you and me

There are people dying
if you care enough
make a better place
for the living
make a better place for you
and for me
