Just posting a fun little idea (move if it belongs somewhere else). If you could pick one song to be the theme of any faction in the game (the major ones mainly) which would it be and why? For me:

• Minutemen: Citizen Soldier for the mere fact that they are citizen soldiers.
• Brotherhood: Thinking Cult of personality because Cult of Maxson.
• Institute and Railroad: can't think of anything.

BoS: Dawn of Battle, Manowar

Forged: Fuel, Metallica

Vanilla Raiders: Leather Rebel, Judas Priest

Minutemen: Highwayman, Willie Nelson

Institute: She Blinded me with Science, Thomas Dolby

Railroad: Buffalo Soldier, Bob Marley

EDIT- Atom Cats: Louie Louie, The Kingsmen

Minutemen- Devo Corporate Anthem

BoS- Wumpscut: War

Railroad- Iron Maiden: Run To The Hills

Raiders- Alice Cooper: No More Mr Nice Guy

Oh and cant forget Super Mutants- Fear Factory: Genetic Blueprint

I always think of this scene from American History X when I think of the Brotherhood. (Warning: LANGUAGE, RACISM, HATE)

Railroad: [censored] Authority by Pennywise

Institute: Mr. Roboto by Styx

Minutemen: Imagine by John Lennon

these are all very great. Just bumping for now, hoping more show up.

I am going to throw in a minor faction: The Children of Atom get Radioactive by Imagine Dragons from me.
