This may or may not be the right section.

Either way, with the Fallout:New Vegas radio, I was wondering if it is possible to add custom songs.
I found the radio's songs directory in the data folder, and was wondering if the song's data are referenced by the game code directly, of if it simply takes one file at a time randomly from that folder (in which case custom music would be simply added).

So, is custom tracks a possibility?
Thanks for the time
