Looks like lots of them do keep alives of that exact packet
alert tcp $HOME_NET any -> 126.96.36.199/23 any \
(content: "|45 5F 00 03 05|"; offset: 0; depth 5;
msg: "Audio Galaxy keepalive?")

Since you work at a school, I have probably the same problem of
tracking hoggish users right now and you may wish to try out
http://ipaudit.sourceforge.net to find bandwidth hogs. It's designed
for that :-)
