I know what you mean about Mr. New Vegas...half the time I don't even listen to the radio, it's either loud mouth or the mutant...both of them scare my little brother :banghead: who intently listens to the lovely music
http://fallout.wikia.com/wiki/Mojave_Music_Radio could serve all your non mutant, non loudmouth computer guy non scaring the little brother needs! Plays Tabitha's playlist without any talk news or Dumb Dumb rants, though to be honest i kinda like her station and am sad when I lose it....
Zion creeps me out a little for the fact there is no radio, well except Elijah's station from Dead Money.... listening to that while running around there is very odd.
There should have been an option to tell Follows-Chalk to become the Zion National Park DJ.... there were enough ranger stations with radios to set up in I'm sure.
