Hi,
Four years ago someone ask a similar question and I gave my solution:
I created a shortcut to my subsonic -server like this:
http://
myserver.subsonic.org/login.view?
user=subuser&password=MySecretObviously you need to change what is in bold to match your settings.
This way you don't have to retype username and password every time you log in to Subsonic.
There's a nifty little program called Shortcut
http://www.optimumx.com/downloads.html#Shortcut which you can use to create an encrypted shortcut.
This prevents anyone from reading your username and password in the shortcut.
