13/37 songs on Diamond City Radio are reused from Fallout 3 apparently. While that's not the exaggerated 90% it is a good number of 'heard-it' songs in-game. The mods coming for additional and/or different music is going to be stellar. Once the G.E.C.K. releases in 2016, the flood of mods will come overall.
I love those dear hearts and gentle people, who live in my home town. Because those dear hearts and gentle people will never ever let you down.I'm so happy they included the song used in the Fo3 trailer, finally in-game Fo4. Love the cheery mood of it.
Just try not to get addicted to Fallout 4 like a drug
