1999
don't go breaking my heart
free up your mind
what i am

2001
a girl like me
a world without you
been there, done that
better be careful
close encounter
high on love
i don't know
invincible
merry go round
she was a friend of mine
spell it o.u.t.
sunshine on a rainy day
take my breath away  
we're not gonna sleep tonight
what took you so long?

2002
baby love
