I had planned to post a song in an administrator's sticky or something alone those lines, but there is none. Can somebody point me in the right direction?

There is no sticky thread for "music I want to have in Vegas".

Then an administrator should put one! >:O

The song I felt needed mentioning was Tony Bennett - I left my heart in San Francisco.

well the closses to something offical would be to find the latest "what do you want in New Vegas" thread and post a list of songs there.

Tho so close to release I doubt they could really add new songs.

Ralos is right, http://www.gamesas.com/index.php?/topic/1111227-what-do-you-want-in-new-vegas/, or http://www.gamesas.com/index.php?/topic/1114877-music-you-would-like-to-hear/. In the future if you have questions like this it's better to send one of the moderators a PM than to start a thread.

(Ralos is probably also correct about his second point, this close to release I imagine the music has been decided.)
