i just added rosario+vampire sounds for my comp and i thought i'd add ...
here are the sounds for download: link & link

Ты can play them on your media player to see if Ты like.

to add them as system sounds: start button > control panel > hardware and sound > change system sounds

under the 'programs' list, pick the sound Ты want to change. i picked 'device connect' (click 'browse' and find wav). then i picked 'device disconnect' and added the other wav sound. 'exit windows' is another good one to change.

save ur new sound scheme before Ты click 'okay.' done.
