Song lyrics interpretation

City lights don't shine as bright when were apart
baby you have got the keys to my heart
promise that you'll never leave me in the dark
and If I need your light be my star
This is the opening verse and is made very powerful so when you first hear it, it makes an impact on you. The first line suggests that the people who are in 'love' when they are apart the lights don't shine as bright.

you say you love me, love me, love me
but that don't do nothing for me
you've gotta do more than tell me what ur feelin
cus if u want me, want me, want me,
I better become ur only
that's the only way that ill be waiting ohhhh
This verse builds up to the chorus empathizing that the guy needs to make more effort and show that he loves her. Females could relate too this part as many have gone through the fact of liking someone but wanting them to like you back.

cus I would just die without it, and there aint know doubt about it
your love, your love, your love
cus I would never make it without it, and there aint know doubt about it
your love, your love, your love
This is the chorus and females could again relate to this part as it is talking about her not being able to cope without his love. This is reinforcing the idea of women needing or wanting a man in their life to love them. This part of the song becomes very upbeat and loud compared to the rest and the rhythm is sped up. 

like a flame that flickers in
come on light my fire
love me like there is no end
till the end of time
This is the part of the song which changes rhythm and becomes more dark and mysterious, suggesting a change in the relationship.

you say u love me love me love me, but that don't do nothing for me
you've gotta do more than tell me what ur feelin
cus if u want me, want me, want me, I better become ur only
cus that's the only way that ill be waiting ohhhh

cus I would just die without it, and there aint know doubt about it
your love, your love, your love
cus I would never make it without it, and there aint know doubt about ityour love, your love, your love
