Ode to Greed is a random song in the playlist.

It is just the Assault part of the soundtrack. It doesn't represent anyone in the Assault. It's for you to have a background theme.

It's part of "Ode to Greed", the theme of the Big Bank Heist.
I guess you have set the game to random song.

It actually fits the style of the building the heist takes place in

Short answer: Yes. It is related to cops assault states including the spawn and when they will stop spawnning.

Long answer:
Normally there will be around 5 assault states in this game but the assault panel on your top right will show only "POLICE ASSAULT IN PROGRESS". Those 5 assault states are

• Control: A break time for us heister. Still. There will be some cops spawn in this state iirc. Correct me if I am wrong
  
• Anticipation: Cops starts to come into an area
  
• Build: "POLICE ASSAULT IN PROGRESS" started in this states. Cops will spawn a lot.
  
• Sustain: As its name. This state. Cops will keep attacking us and they will keep spawning a lot.
  
• Fade: Enemies won't spawn in this state. You can extend this state if you know how to and you can know when it is on this state when a bot said "The cop is retreating"

You can know it from the song that has been changed the tune of its sound. More info you can read more in: https://www.reddit.com/r/paydaytheheist/comments/25ugvm/explanation_of_assault_wave_mechanics_credit_goes/

Note that in some heists we will have Endless Assault or Point of No Return as well.

Or yeah. If he meant that then don't mind my long answer xD

IIRC. The opera will play on "Build" state.
