Some music albums get released as different versions, like a UK release and a US release. I had a couple Beatles albums that did not get indexed by Boxee because I just have the mp3's and folders labeled with the album name and not "Album Name [UK]", which is how allmusic.com lists them.
here's my folder structure:
/music/The Beatles/1965 - Rubber Soul/
/music/The Beatles/1966 - Revolver/
Allmusic doesn't have a listing for just "Rubber Soul", they only have them with the country indicator like this:
- Rubber Soul [UK]
- Rubber Soul [US]
- Revolver [UK]
- Revolver [US]
In these examples, the the different releases have different tracks - maybe that can be used to figure out which is which. Or maybe you can identify the country code in [x] and assume that would not be included in someone's folder name or ID3 tags. Or, I think usually one of the different versions is considered the "main" version of the release, and the other an alternate, maybe you can default the indexing to the main version unless the country code is included in the name?
Let me know if you want to see my boxee.log and I can PM it, there are tons of other album indexing errors in there too.
