It adds to the emotional depth of the game. Fairly catchy on its own, but it also acts as an ironic, and tragic, contrast to the main character's situation. "The Wanderer" by Dion & The Del Satins."Atom Bomb Baby" is a great song to listen to while wreaking havoc in the wasteland.A somber song that greatly fits the apocalyptic setting and the Sole Survivor's situation. "The End of the World" by Skeeter Davis.There's a good reason it was used for the game's launch trailer. "Dominant Species", one of the combat tracks, is an epic remix of the main theme.
The Institute's theme ("Imagine Utopia"), which has a fittingly futuristic and hopeful sound with an also fittingly sinister, mysterious, and apprehensive hint to it."Still Standing", one of the Minutemen themes, which strikes just the right chord between hopeful, militaristic, and heroic."Rebuild, Renew" and "Of the People, for the People", two of the city themes, both of which convey the feeling of a wasteland society that is rugged, but with hope for rebuilding.An epic rock cover made it more wild with guitar riffing. The main theme is very atmospheric and packs some serious punches."Begin Again", featured in the Dead Money expansion pack, is a haunting song that espouses the main theme of the Sierra Madre - letting go."Blue Moon", The first song that plays in the game, has the classic Vegas feel to it.
