Seventeen

Okay, I will go line by line. I think this is about her father.

Used to be a major scale, But the melody went stale, Musical cacophony let, Insy Winsy spider free.

She is using music, which is her passion, to tell about how she was once her fathers life, then she got older, and he lacked interest in her. Then she got sent free.

You're a rich little boy, Who's had to work for his toys, You've got all the sensibilities, oh, Of an upper class guy.

Her father has money, and girls like him for his money, which he had to work for. He is an asshole just like most people with money.

No, no I'm not your little slave, No I don't twist and turn that way, Only got bad things to say, You're always asking what is up, up with me,

She is saying how she wont turn out to be money crazed, and how he wants her to be, for this he criticizes Marina, saying only bad things. He might not think he is hurting her, so he asks whats wrong, unknowing of her depression.

Could never tell you what happened, The day I turned seventeen, The rise of a king and the fall of a queen, Oh seventeen, Seventeen.

In this part of the song, she gets happy. People seem to think it is about rape, but it would be slower... I don't think she would be able to stay emotionally stable when singing about it. I think the rise of the king is saying a connection to "a hassle free life". The fall of the queen is her moving out and not having the money support and having to live and support herself.

You want a hassle free life? Go get your upper class wife, She's got all the personality, oh Of a lemon that has been. Truly sucked dry.

This is saying he got re-married after the divorce and she now has a step mom she isn't fond of, most likely because she is using him for his money. She bores Marina and can read her and doesn't have a personality.

Oh, you were embarrassed of me, 'Cause I used my tongue freely, Bet you wish I couldn't speak, 'Cause when I do, you know, I tell you why you appear weak.

She is saying that she used her tongue to point out true flaws of her father and how she is mad at him and depressed, most likely in front of others.

You teach me how to behave, I felt you question the way, I was brought up as a baby, Well you don't know fuck about my family.

I think that is speaking to both step mom and dad, her step mom tried to teach her to be classy, and probably said rude things about her mother. She is saying the step mom doesn't know anything about her family.

and the chorus

Never felt like a princess, I used to kill myself in this dress, That it was just how things, Were meant to be, Oh seventeen, Seventeen.

In teen idle, she sang about being depressed and suicidal at 16, this probably lasted for awhile and she would try and tell herself things were ok by saying thats how it was meant to be.She never felt good about herself, but when she was able to leave at 17, she felt released.
