Just a little kanji and romanization.
If there are inaccuracies, either post or (Mare/Jomei) feel free to edit my post directly.

REQUESTING TRANSLATION, LOL.
It seems fairly simple, but there are grammatical elements that I haven't quite learned/mastered yet...

君が笑う夢を見たよ
君が笑う夢を見たよ
ここは狭くて暗い部屋
鍵をかけて鍵をなくした


僕らは何を置いてきたの
僕らは何を忘れてきたの
電車が走るのが見える
飛行機雲が消えてゆく


ひかり ひかり ひかり
君をつつめよ
ひかり ひかり ひかり
僕を置いてけよ
行けるかな 君のいる場所へ

君の首を絞めていたよ
君の首を絞めていたよ
君は「殺して」と言う
君はいつかの僕だったんだ

ひかり ひかり ひかり
君をつつめよ
ひかり ひかり ひかり
僕を置いてけよ

行けるかな君のいる場所へ
行けるかな光のさす場所へ

10 minute version! (I'm... bored and it looked pretty simple.) I'm not sure about the two lines that end in 'datta'n da' because they mix 'itsuka', which refers to the future, with the past tense. Which is weird.

I saw a dream where you smiled
I saw a dream where you smiled
This room is dark and cramped
I don't have the key, I lost the key

What is it we left behind?
What is it we forgot?
I can see the train going by
The smoke trail will disappear

Light light light
It will engulf you
Light light light
Leave me behind
I wonder if I can go to where you are

I strangled you
I strangled you
'Kill me' you said
(not sure here... )

I strangled you
I strangled you
'I love you' you said
(not sure on this line either...)

Light light light
It will engulf you
Light light light
Leave me behind

I wonder if I can go to where you are
I wonder if I can go to where the light shines

night rider?

Kanji:

キミからメールが来ないから
キミからメールが来ないから
今夜も僕はねるれないんだ
一生メールが来ないから

一生メールが来ないから
一生メールが来ないから
一生僕はねむれないんだ
クールなメールが来ないから

目をとじて　横になって　キミをおもう
再生ボタン　押したとたん
キミはうたとひとつ

キミは僕のうた
キミは僕のうた
やんなっちゃうな　しょっぱくなっちゃうな
suicideしちゃいそだな

目をとじて　息をとめて　幽体離脱
再生ボタン　押したとたん
キミはうたとひとつ

キミは僕のうた
キミは僕のうた
やんなっちゃうな　しょっぱくなっちゃうな
suicideしちゃいそだな

しょーもない写メールを撮って
キミに送るよ
喜んでくれるかな
ねえ　ほんとは僕　こんなんだよ
キミを守る　夜の使者
正体はナイトライダー

ナイトライダー
ナイトライダー
泣いてないさ
ナイトライダー

There's a few typos in them thar lyrics.

Post redacted since Mare has FINALLY gotten around to looking at my horrible second translation.

Because your mail hasn't come
because your mail hasn't come
again tonight, I can't sleep
because mail hasn't come all my life

Because mail hasn't come all my life
because mail hasn't come all my life
all my life, I haven't been able to sleep
because cool mail hasn't come

I close my eyes, lay down, and think of you
As soon as I press play
you are one with the song

You are my song
You are my song
Don't become unpleasant, don't become wearisome
I feel like I'm going to commit suicide

I close my eyes, stop my breath, and have an out-of-body experience
As soon as I press play
you are one with the song

You are my song
You are my song
Don't become unpleasant, don't become wearisome
I feel like I'm going to commit suicide

I take a pointless picture on my phone
and send it to you
I wonder if it'll make you happy
Hey, the truth is, this is what I'm like
An emissary of night who protects you,
I'm really the Night Rider

Night Rider
Night Rider
I'm not crying
Night Rider
