If we are counting Mods my favourite has to be Conelrad but I also like the pirate radio from project brazil which played rock and metal music.

The mysterious broadcast is without a doubt my favorite radio station, I just love walking the wasteland with those sweet jazz tunes blowing through my pipboy. god I love that smooth groove when I'm blasting fiends back to the grave. And of course it's way better than having to listen Johny Guitar all the time.

For vanilla, I listen to Radio New Vegas. He has the voice that makes you feel safe...until you get raided by giant Radscorpions. For modded, I like to listen to Deathsong Brotherhood's Radio Underground, the mod is excellent and all, but the one thing that always keep me from removing it from my load order is Radio Underground. If you heard that woman's voice, you would know what I mean. Steal my heartbeat. steal my blood flow. still my hearts racing, waiting for your blade again...and again.

Gives me shivers and the feels at the same time man.
