Recently I improved YADB to better handle resubmitted CDs. The theory was that when you find a CD with less that perfect data, you fix the imperfections and resubmit it. The changes would then replace the old data (instead of living along side of it like before).
This breaks in actuality sometimes, I found a couple of cases last night. There was a Cat Steven's disc that had been erroneously submitted as a compilation, and when I resubmitted as a non compilation, it didn't replace the data (it assumes that compilations are different thatn compilations). And Santana's Supernatural had a similar problem (a lot of the tracks have guest artists, so it could be considered a compilation, though it isn't). But it had a couple of other problems: one of the submissions had bogus track names (like "a" or "c"), and these are different enough that the system decided the CDs were different and added a new one instead of replacing the old one with bogus track names. The other problem was that one entry had the artist name in the song title (for the tracks with guest artists) and this is enough of a difference for the CDs to be considered different.
So I wrote a couple of tools that let me figure out which is good and delete the other.
When you do a YADB lookup, and get multiple results, post the artist, title, time (and IP if you know it) here, and I'll take a look. If there is enough interest, I'll hook the tools into a web page and try the volunteer approach again.
