About the sound folder...

I'm wondering which sound is the sound that makes the metalic noises when you log on, like when you type in your account name and password and shit, i would listen to all of them but yeah would be a lot easier if someone just knew

its the
key_1 - 8kb MP3 format sound
key_2 - 9kb MP3 format sound <-------- this one makes the metalic sound when you type you acc/pass every time you log in
key_3 - 8kb MP3 format sound
in the sound folder

And if you ever get sick of the login screen music, just look for the music file and delete it.
