les miserables songs

recently i became very addicted to the songs in les miserables the musical. the ones which i love so much are titles like " the dream i dreamed" " a heartful of love" " in my life " . I wonder why ppl don put this kind of songs in the karaoke to sing . I love to sing this type of songs, also like phantom of opera.

this is the link to one of the songs " the dream i dreamed "

this song is sung by the character name " Fantine" whose fate was so ill, her husband left her with a child, and she is forced to become a prostitute, and she showed so much emotion in this song.

these are the lyrics:

There was a time when men were kind
When their voices were soft and their words inviting
there was a time when love were blind and
the world was a song
and the song was exciting
there was a time...
then it all went wrong

i dreamed a dream that time gone by
when hopes were high and life worth living
i dreamed that love will never die
i dreamed that god will be forgiving

i was young and unafraid
when dreams were made and used and wasted
there was no ransom to be paid
no songs unsung no wine untasted

and the tigers come at night
with the voice as soft as thunder
and they tear your hope apart
as they turn your dream to shame

he slept a summer by my side
he fill my days with endless wonder
he took my childhood in his stride
but he was gone when autumn came

and sitll i dreamed he 'll come to me
we'll live the years together
but there are dreams that cannot be
and there are storms we cannot weather

i had a dream my life would be
so different from this hell i'm living
so different now from what it seems
now life has killed the dream
i dreamed
