Attention CD lookup software authors!

We’re getting a number of reports from Rhythmbox, Sound Juicer and other applications that their CD lookup is no longer working. We currently have no open bugs that tell us what is wrong, so we can’t fix anything.

We believe that we are outputting correct XML for CD lookups, thus there isn’t anything for us to fix. We are, however, outputting more matches for CDs, since multiple releases for a single CD can be returned. But, this is nothing new — clients should’ve supported this even before NGS.

We need the authors of programs that are broken to tell us what broke their stuff. Then we can determine if we need to fix something, the authors need to fix something or if we can come up with some sort of compromise. We’ve been talking about NGS for two years and these application authors never bothered to test their applications with our new stuff.

End users who are upset at CD Lookups failing: Please go complain to your software authors to resolve these issues or file bug reports with us if the trouble is in MusicBrainz.

NOTE: These applications are not failing because of User-Agent blocking — we haven’t actually started doing that.
