In my opinion, at this moment Banshee has the best implementation of all available players for Linux out there. However, I still cannot let Banshee fully manage my library (i.e. let the application rename files and paths on import), since there is no way to sufficiently describe my preferred library structure.

So far I have files from a single CD be filed as:

LibraryPath/Album Artist/Year -- Album Name/Track -- Track Artist -- Track Title

But for albums with 2+ CDs, the scheme is as follows:
LibraryPath/Album Artist/Year -- Album Name/Disk Number/Track -- Track Artist -- Track Title

I would appreciate greatly the possibility to configure the folder_pattern to be something like:

%album_artist%%path_sep%[%disk%%path_sep%]%year% -- %album%

where the part between [ and ] would be added to the path only if the ID tag has a frame of this type (whatever pattern the user enters) AND it is not empty. Otherwise this part of the pattern would be skipped.

I hope I didn't give any confusing explanation of my idea and would see it as an implemented feature soon.

Best regards,

Todor
