started some test of multi-album and see that for an album smart playlist, the context menu doesn't offer "change info provider" nor "rescan all".

Odd, I see both on albums and artists smart playlists. Could you look a this again, is it something about the playlist rules? Could it be skin related (I'm using Confluence) how content is set? I don't see why this would not work for you but does for me.

As you go on to describe it is a useful and flexible thing to be able to do.

As an aside, could you remind me what the bScrapedMBID is used for?

It flags if the artist or album mbid came from scraping e.g. a name lookup then taking first match so could be wrong, or from embedded tags in the music files (taken as definitive).

When doing refresh from the info dialog, if bScrapedMBID is true then the lookup by name is done again (rather than use the mbid) to allow mistaken identity to be corrected. The merge processing also takes care to only overwrite mbid if it was empty or scraped.

Thank you for testing and reviewing this in detail, it is appreciated.
