If you subscribe to Toronto Symphony Orchestra's mailing list they will provide you with free access to the Naxos Music Library! (They call it "Beethoven On Demand)
Yes, I know it sounds "to good to be true. Oddly, I am already a subscriber through my workplace - won't bore you with the details. However, I have just checked it and it does indeed seem to work. Presently listening to the Neuhold's Gotterdammerung.
I cannot guarantee of course that you won't get spammed to your email but I have not received anything else and given it is the TSO it would seem unlikely.
If you wish to try it out, go directly to the TSO "subscribe to email" page by clicking here (direct url: http://www.tso.ca/Plan-Your-Experience/EMail-Club.aspx.If you don't trust direct links (yes I know people are paranoid) google "Toronto Symphony Orchestra" and on the home page, on the right hand side, click "Join The TOS Email Club" Dirct link to page here)
If you can, you might want to check out their performances while you are there.
Postscript: I just remembered, includes BIS and Chandos catalogs also - among others
