limit offered albums by a tag..?

Entering "John, Martin" for the Person tag produces a single value of "John, Martin". For this to work correctly, you need to create two Person tag values "John" and "Martin".

Different tagging programs have different ways of doing this. Which tagging program are you using and what is the format of your files (FLAC, MP3, AAC, WAV, etc.)?
