..we don't need to know the way home.

All we want is life beyond

There should be entire map covering radio station playing songs like that from popular post apocalypse movies

Modders! You know the drill!!

1) Copright Issues
2) Not lore. The world of Fallout got stuck in the 50's, and the 80's we know was never present.
3) Mediaplayer of choice. If you want certain worldwide music while playing, why not mute the ingame music and fire up your own songs?

But new music is being written in the post-apocalypse. See the bar in Goodneighbor.

Its all about the feeling man! We all grew on movies and books with post-apocalypse theme. Why not bring them close together
