I believe we can use a lot of adjectives to describe this acoustic version of 3am, even more because in the beginning of the video he explained the real meaning of the lyrics!
She says it's cold outside and she hands me my raincoat / She's always worried about things like that / She says it's all gonna end and it might as well be my fault / And she only sleeps when it's raining / And she screams and her voice is straining /
(chorus) She says baby / It's 3 am I must be lonely / When she says baby / Well I can't help but be scared of it all sometimes / And the rain's gonna wash away, I believe it /
She's got a little bit of something, God it's better than nothing / And in her color portrait world she believes that she's got it all / She swears the moon don't hang quite as high as it used to / And she only sleeps when it's raining / And she screams and her voice is straining /
She believes that life is made up of all that you're used to / And the clock on the wall has been stuck at three for days and days / She thinks that happiness is a mat that sits on her doorway / But outside it's stopped raining /
