i find 2 extra meaning of "right here waiting for you".

1.aliens sings this song to humans.
"oceans apart"stands for the universe, the distance.
"Day after day"means it takes a long time for aliens & humans to find each other.
"i hear your voise on the line"receive signal through some means of microwave,etc.
"Wherever you go whatever you do i'll be right here waiting for you"clear enough,wherever humans move to which planet in the future, they aliens will be in their galaxy waiting for us.
"whatever it takes or how my heart breaks"because humans do alot bad things & maybe evil,but they will take all cost to contact us.that's why "i wonder how we can survive this romance but in the end if i'm with you i'll take the chance."
"i took for granted that would last somehow"has 2 meanings.one is that they believe the extinction of humans.the other is that they believe the friendship of aliens and humans would last.
why they "heartbreaks"?because they know humans are bad & danger,those war violence thing,you know.but they still want to make friends with us, even be destroyed by human--it makes me cry.

2.someone in the future sings this song to the people at present."day after day"means they are from the future."hear your voise on the line"the technology is highly advanced that they could hear present people talking on the monitor.and wherever people go or whatever people do they will be right there in their time,world or whatever.(similar to explain 1).

Here is the song "right here waiting for you"
oceans apart
day after day
and i slowly go insane
i hear your voice
on the line
but it doesn't stop the pain
if i see you next to never
how can we say forever
wherever you go
whatever you do
i will be right here waiting for you
whatever it takes
or how my heart breaks
i will be right here waiting for you

i took for granted
all the times
that i thought would last somehow
i hear the laughter
i taste the tears
but i can't get near you now
oh can't you see it baby
you've got me going crazy
wherever you go
whatever you do
i will be right here waiting for you
whatever it takes
or how my heart breaks
i will be right here waiting for you
i wonder how we can survive
this romance
but in the end if i'm with you
i'll take the chance

oh can't you see it baby
you've got me going crazy
wherever you go
whatever you do
i will be right here waiting for you
whatever it takes
or how my heart breaks
i will be right here waiting for you
waiting for you

I dunno ... the alien sounds a little possessive ... love struck ... psychotic?

Richard Marx! Wow. That song brings back memories. None of them alien related.

This song had/has one meaning and one meaning only.... Richard Marx was/is pining over a woman...

Sorry XJX, but you may have alien on the brain, my friend. Let's not get carried away...
