If you haven't already, check out my favorite band called The Head and the Heart. They're so hopeful, but in a way that lets you know they've struggled. Like in "Another Story" (

I see a world
A world turning in on itself
Are we just like
Hungry wolves howling in the night
I don't want no music tonight
[...]
I'll tell you one thing
We ain't gonna change much
The sun still rises
Even with the pain

I'll tell you one thing
We ain't gonna change love
The sun still rises
Even through the rain

Another great one to listen to when you're depressed is "Library Magic" () the core of which is "there will always be better days."

God, I love that band. <3

Edited to add: Thanks for the link of that youtube video. Have you watched the official video? Incredibly depressing and just doesn't do the song justice.
