No one here is explaining why they like the particular song, so I'll take my best crack at it.

For me, the song is "Edit the Sad Parts" by Modest Mouse.

Just to start, the song feels like it was written specifically so that you can listen to it when you're upset. It channels that emotion so well. The first riff starts off slow, whiny, and sounding pathetic almost. Then just a moment later the guitar picks up, and I swear, it feels literally like a punch in the chest.

Then the lyrics. Oh my goddamn, the lyrics. Isaac Brock has this gift, that I don't think anyone else quite has to the same extent, of writing relatable lyrics, without being cliche. That's why I love Modest Mouse as much as I do – everything that they write, anyone can relate to, but it's not something that you've ever heard put that way before. So, onto the lyrics.

"Sometimes all I really wanna feel is loved.  
 Sometimes I'm angry that I feel so angry."

This is fucking perfect. It just captures the feeling so well. When you're depressed – really, truly, tying the noose depressed, this is exactly how you feel. You're not just lonely, but you hate yourself for feeling that way. You hate everyone and everyone and everything and the only person you blame for any of it is yourself.

 "Sometimes my feelings get in the way.
 Of what I really feel I needed to say."

This line is delivered in a self-loathing kind of way that suits it perfectly. Isaac Brock might not be confused for Freddy Mercury, but I don't think that anyone else could deliver this line with as much emotional power.

At this point, the song kicks up in tempo, the guitar gets rougher, and Isaac starts screaming.

"When you stand in a circle
You'll all have a back to bite"

Feelings of betrayal, backstabbing, and sooooo much cynicism. Everyone's stabbing everyone in the back. Trust no one. Fuck the world and every single living thing on it. GRRR!!! ANGST!!!

"Back logged books on the seven wonders"

Longing to get away? I heard one theory, which I would absolutely love to include were I to make a music video for this, is that this song is about him longing for someone who has killed themselves, jumping off of the Golden gate bridge (which is featured on the album cover. Probably not what Isaac had in mind, but still a really cool interpretation).

"We're all so funny but he's lost his joke now."

When you're depressed, nothing is funny. No one can cheer you up. Everyone might be funny, but when you feel down, you don't want anything to do with anyone.

"Our communications come in one-lined jokes
From stand-up-comics and rock musicians
Making so much noise you don't know when to listen."

Have you spent any time on reddit? Then you can probably attest to this. Even in real life, a lot of humour among friends just includes quoting movies that you've all seen, or songs you've all heard (yes, I get the irony in this). Isaac longs for something more fulfilling, something of substance. But we're all so busy trying to be funny that we lose the forest for the trees.

"Why are you judging people so damn hard?
You're taking your point of view a bit too far."

This is funny to me, because suddenly he does get the conversations of substance, but he feels it's being taken too far. Why are you judging people? Why are you being so critical? He's being intentionally hypocritical, and I love it. Because when you're depressed, you're the most hypocritical person ever. You hate everyone, and demand their love. When someone tries to be kind to you, you respond with bitterness.

"I made my shoes shine with a coal,
But the polish didn't shine the hole"

I like the imagery here. First of all, the image of using coal on your shoe to make it shine. You're using something known for being dark and staining, but it does the trick when you use it on a shoe. The implication, though, is that he's trying to use darkness to make his life shine bright. And it might even work sometimes! But no matter what polish you use, the hole is still going to be there, and nothing can fix it.

Now the song changes again, and the lyrics get more hopeful.

"Think it over. There's the air over the height of the high rollers."

Don't give up on life. Shoot for the stars. Aim high, there's plenty of room for you up there.

"Think it over. You ain't got nothing till you know her."

This line is only on the live version, but I love it so much that I'm including it here. After this line, I imaging the character getting up off his ass, and getting the confidence to finally do something with his life. He's taking his depression into his own hands!

And then, silence.

The sad part, his failure, is edited out.
