Thanks for asking.
Daniel is right. Live Station doesn't have a bundle identifer, which 
is THE standard means of locating and identifying an application under 
OS X. You can add one yourself by f.ex. inserting a
<key>CFBundleIdentifier</key> 
<string>com.livestation.livestation</string>
into the Info.plist's main dictionary. The real solution, of course, 
is for LiveStation.com to fix their Info.plist at which point, it can 
be identified easily by Remote Buddy and many other apps.
