Hopeless Opus Lyrics
Cherry bomb head strong I could fake my own death
Hey Mr. Fate Man shuffle me a ninth life
I’ve been wrong, go long
Throwing me a sharp right
It’s not a picture perfect life
Not what I had in mind
Let me write my own line
That I’ve filled with empty space
Oh I’m trying not to face what I’ve done
My hopeless opus
I’m in this race and I’m hoping just to place
Oh I’m trying not to face what’s become of me
My hopeless opus
I could slide take a dive take it for the home team
Hey Mr. Postman slip me one more green note
I’ve been low hit the floor looking just to make broke
It’s not a picture perfect life
Not what I had in mind
Let me write my own line
That I’ve filled with empty space
Oh I’m trying not to face what I’ve done
My hopeless opus
I’m in this race and I’m hoping just to place
Oh I’m trying not to face what’s become of me
My hopeless opus
Hey Mr.
Hey Mr. Cage Man
Cherry bomb
Let me
Cherry bomb
Cherry bomb
That I’ve filled with empty space
Oh I’m trying not to face what I’ve done
My hopeless opus
I’m in this race and I’m hoping just to place
Oh I’m trying not to face what’s become of me
My hopeless opus

Let me start out by saying "opus" is Latin for work, meaning the song's title means "hopeless work". This means that the man feels like his work isn't going anywhere. Next, throughout the song you hear him mention 4 men, Mr cage-man, Mr safe-man, Mr Post-man, and Mr Fate-man. The singer feels like these people are controlling his life, first, Mr cage-man. The line "Hey Mr. cage-man, let me take a fresh breath" implies that the cage-man is making him feel trapped. The next one, "Hey Mr. safe-man, shuffle me an okay" means that the singer is settling for average, but he is bargaining to do so. Third, the post-man, the line "Hey Mr. post-man, slip me one more green note" is a bit hard to figure out, but then I found out green note is a website where you send donations to students struggling after college with either student debt or finding a job that fit's their skills. This means the singer is saying he's having money problems and/or can't seem to use his skills. Lastly, the fate-man. He's mentioned in the line, "Hey Mr. fate-man, shuffle me a ninth life." The first thing I noticed is that a cat is said to have 9 lives, but that isn't true. This could mean that he is asking for something he doesn't have but want's desperately; more time! But there's one last detail, the singer say's "I've filled this place with empty space, I'm trying not to face what i've done". Finally, this means that he felt like he's done this to himself. He's wrecked his own life, and out of desperation, he gave control to other people, but now he wants out. This song is one of imagine dragons darker songs, but with how deep it is, and how great the melody and rhythm is, it's also one of their best!

First, I'd like to point out that the definition of "opus" is a creation, so the name means "hopeless creation." I didn't know what that meant, so just wanted to touch up on that.
I believe this song is about someone trying to change their life but feeling unable to, hence the reason that this creation is "hopeless." Not only does it ask "Mr. Fate man" to give him a ninth life (a second chance, or in this case, a ninth or maybe more) but also permission to "write [his] own line," meaning take take control over his own life.
This song is really similar to Always Something from Cage the Elephant, granted that Always Something is a bit more dark. This song is talking about how this person has pretty much destroyed their own life with help of fate. Always Something is talking about how even when life is going perfectly, something always steps in the way and ruins it (wife having an affair, homeless person murdering him, etc).

As some people have already said, "opus" means "work (of art)." And seeing as Imagine Dragons writes their own music, I think this song is about someone who got famous on their own and then started to gave in to their own fame and became a figurehead of sorts.
So, I'm going to start with the chorus because the chorus almost always holds the main point of the song:
It's not a picture perfect life Not what I had in mind // These two lines refer to the lifestyle of someone famous, and how it's not perfect at all Let me write my own line // This refers to the fact that the narrator wants to write their own music instead of preforming the music of others.
I've got this place That I've filled with empty space // This would refer not to a physical space but the "place" in the artist's head where they used to write music. Oh I'm trying not to face what I've done My hopeless opus // The opus that's mentioned wouldn't be a song but the artist themselves, hopeless because they aren't really famous anymore but rather just someone who displays the work of others. I'm in this race and I'm hoping just to place Oh I'm trying not to face what's become of me // "What's become" of them is that they've started to not be themselves anymore, and they don't want to face that. My hopeless opus
Now, to the first verse:
Hey Mr. cage man let me get a fresh breath // "Mr. Cage Man" would probably refer to an agent or someone who's pressuring the artist into not being themselves. The artist wants a fresh breath so they can start writing their own music again. Cherry bomb head strong I could fake my own death // By faking their own death, the artist would be free of the constraints put on them and they could write their own music. Hey Mr. fate man shuffle me a ninth life // They're asking for a "ninth life" so that they can become someone new and write their own music. I've been wrong, go long Throwing me a sharp right // The sharp right would be the sudden change from writing their own music to preforming the music of others.
Next:
Hey Mr. safe man hustle me an okay // If "Mr. Safe Man" hustles them an okay, they'll know it's safe to go back to writing their own music. This refers to the fact that it would be the safe thing to just keep preforming the music of others. I could slide take a dive take it for the home team // "I could slide" means that they could lose their fame. I'm honestly not sure what the other things mean. Hey Mr. postman slip me one more green note // They want to keep getting paid even if they go back, so they're asking the postman to give them one more "green note" or paycheck. I've been low hit the floor looking just to make broke // They've been low probably as a struggling musician before they became famous. "Hit the floor" would be in the present, which is a metaphor for what would happen if they lost all their money. Again, I'm honestly not sure what the other stuff means.
In total, I think this is a song about how musicians feel pressure to stop being true to themselves once they become famous. It's very possible that Imagine Dragons themselves were pressured into preforming music not written by them, but they write their own music for the most part and it always shows through in their songs.
