As great as the music selection is in Fallout 4 is, it can get a bit repetitive! After my time with the game, I don't think I'll ever get the song "Atom Bomb Baby" out of my head! Now that the Far Harbor DLC is out, Reddit has uncovered a radio mod that can better help you keep your sanity. This Nexus mod adds 286 songs ranging from the 1930s to 1960s, and they all are lore specific to war and atomic energy and stuff like that.
The song list has plenty of people you don't recognize on the list, but among those who stand out. you'll see Bing Crosby, Jerry Lee Lewis, Ella Fitzgerald, Louis Armstrong among other big names. According to the mod maker, all these songs are labeled under creative commons and fair use. Check out the song list here, and download the mod here.
