About a song lyric


I was looking at the
[lyrics](http://music.goo.ne.jp/lyric/LYRUTND365/index.html) of RCサクセション's
雨上がりの夜空に. My understanding is that this is a song about a person talking to
his/her (personified) car. There are several things I don't understand.

(1) In this line

[code]

    バッテリーはビンビンだぜ
    
[/code]

I understand that バッテリー is mentioning a car battery. But why is `ビンビン` used?
Does it have any meaning related to charging of a battery?

(2) In this line

[code]

    こんな夜に 発車できないなんて
    
[/code]

The person is perhaps sad that he/she cannot ride the car. But why is `発車`
(start moving with the car) used here? I guess it would be more natural to say
that they cannot start the engine, but why is it particularly mentioning `発車`?
Is it normal in Japanese say "I cannot start moving with the car" when they
cannot start the engine or cannot go for a drive?

(3) In this line

[code]

    雲の切れ間にちりばめたダイヤモンド
    
[/code]

What is `ダイヤモンド` mentioning? I cannot make sense of a slit between the clouds
being filled with a diamond. Is it some metaphor?




This song uses "double entendre" everywhere in the lyrics. The explicit
context, of which you are aware, is riding a car, and the implied context is
riding a woman.

I agree with you that ビンビン and 発車 sounds unnatural, when they are only talking
about cars. But I hope you can easily understand what ビンビン and 発射 (the same
sound as 発車) mean in the latter context.

And twinkle twinkle little stars are like diamonds in the sky --- Japanese
people are familiar with that metaphor, too.
