I like GNR and the songs in Fallout 3 better, maybe because I'm a sucker for Bob Crosby and the Ink Spots..but that's not to say NV doesn't have some good songs. (Blue Moon, Jingle Jangle, Big Iron, and Heartaches by the numbers)
I guess it doesn't help I'm mad at NV for crashing when ever I enter the strip, the fort, or the dam meaning I can't complete the game.. :/
