Thanks for the reply!
Interesting,...it does seem dependent on the search term used. I was searching for a compilation and used the term "various". The 404 messge returned led me to believe it couldn't reach the site at all. Searching on the term "various" at the Discogs site does return a list of results.
Here's the URL on Discogs that I was hoping to use data from;
http://www.discogs.com/Various-Deep-Dance-.../release/956553It would be nice to get a more relevant message, or even better, to search not just by artist.
