how can something so upbeat be so depressing?

I came across this song on an indie music site and absolutely fell in love with it. It is called Pumped up Kicks by the band Foster the People. 

Every morning when I head out, the sun’s shining bright and the heat has me enclosed in a tight hug. I love summer. And I plug in my earphones and just like that, I don’t give a care about the rest of the world. 

This song is so upbeat and just so perfect for summer. 

Ahh…doesn’t it sound like the start of a cheesy romantic love chick flick?

BAM!

That’s right. It’s all gone. I had to go online to read the lyrics and BAM! There went my upbeat happy song. It is so depressing!! I’m not even exactly sure what the song is entirely about…but what I make of it is this: Some kid in school, probably one with no friends and anger problems, finds a gun and you literally can see him slowly unravel and go insane and have a high school shoot-out. 

So yea, how can something so upbeat be so depressing?

I still like the song though. It is rather meaningful and deep and touches on the issue of depression. I do feel for adolescents who go through depression. I mean, they’re so young and have so much ahead of them. Yet they feel as though their world is falling apart and they have no one to turn to. So so painful. 

Robert’s got a quick hand. 
He’ll look around the room, he won’t tell you his plan. 
He’s got a rolled cigarette, hanging out his mouth he’s a cowboy kid. 
Yeah he found a six shooter gun. 
In his dads closet hidden in a box of fun things, and I don’t even know what. 
But he’s coming for you, yeah he’s coming for you. 
All the other kids with the pumped up kicks you’d better run, better run, outrun my gun. 
All the other kids with the pumped up kicks you’d better run, better run, faster than my bullet. 

Daddy works a long day. 
He be coming home late, yeah he’s coming home late. 
And he’s bringing me a surprise. 
'Cause dinner's in the kitchen and it's packed in ice. 
I’ve waited for a long time. 
Yeah the slight of my hand is now a quick pull trigger, 
I reason with my cigarette, 
And say your hair’s on fire, you must have lost your wits, yeah. 
All the other kids with the pumped up kicks you’d better run, better run, outrun my gun. 
All the other kids with the pumped up kicks you’d better run, better run, faster than my bullet. 
All the other kids with the pumped up kicks you’d better run, better run, outrun my gun. 
All the other kids with the pumped up kicks you’d better run, better run, faster than my bullet.
