The song interests me

Lyrics:
What do you mean?
Oooh When you nod your head yes
But you wanna say no
What do you mean? Heeey
When you don’t want me to move
But you tell me to go
What do you mean?
What do you mean?
Said we’re running out of time
What do you mean?
Oh oh oh What do you mean?
Better make up your mind
What do you mean?
You’re so indecisive of what I’m saying Trying to catch the beat, make up your heart.
Don't know if you're happy, or complaining.
Don’t want for us to end where do I start First you wanna go to the left and you want to turn right Wanna argue all day, making love all night.
First you up and you’re down and then between
Ohh I really want to know…
What do you mean?
When you nod your head yes
But you wanna say no
What do you mean?
When you don't want me to move
But you tell me to go
What do you mean?
What do you mean?
Said we’re running out of time
What do you mean?
Better make up your mind
What do you mean?
You’re overprotective when I’m leaving Trying to compromise but I can’t win
You wanna make a point but you keep preaching
You had me from the start won’t let this end
First you wanna go to the left then you want to turn right
Wanna argue all day make love all night
First you up and you’re down then you're between
Ohh I really want to know…
What do you mean?
Ooh.. When you nod your head yes
But you wanna say no.
What do you mean? (oh what do you mean)
When you don’t want me to move
But you tell me to go
What do you mean?
I wanna know
Oh what do you mean?
(Ooh) Said you’re running out of time
What do you mean? (ah baby)
Oh oh oh what do you mean?
Better make up your mind
What do you mean?
When you nod your head yes, but you wanna say no
What do you mean? (You're so confusing baby)
Heyyy, when you don't want me to move,
 But you tell me to go
What do you mean?
What do you mean?
Said we're running out of time
What do you mean?
Oh oh oh what do you mean?
Better make up your mind
What do you mean?

3.compromise:

My comments:
The song is Justine written for his ex-girlfriend,Selena. 
I think the melody is brisk and the words reveal Justine's feeling to Selena.
It's a really cool song and  I very like it.
