Alternatives to Amazon?

Can one find and use alternative sites for adding CD? Free base just gives me "502 database error" which I supppose means they are not going to provide information. So I am left with just AMAZON.
When I use "scan" I NEVER find any covers - it briefly searches,but with no result. I have to do Google search. Any way round this? i'm trying to replace lost db. of 7,500 entries ASP.

Try switching to a different FreeDB server in settings (Internet tab). They should work. Default server is temporarily offline.

Also, note that you can always use Download Covers future later to attach covers.
