One of the good things about Firefly compared to WMC is that it has actually useful Composer browsing capabilities. But, like the whole Album Artist vs. Artist (compilation/soundtrack) issue, the Composer tags as filled in by WMP (or others) from the online databases makes it very difficult to actually browse, well, by Composer. These tags are cluttered with multiple artist names, typically their "real names" vs. their band or stage name.
Yes, it's nice to know that "Richard Hall" composed all track on Moby's "Play", but I don't ever plan on browsing composers looking for my Moby albums... I'm only concerned about Composer browsing for classical genres, where it has obvious usefulness. It is my preferred method for browsing these genres...
I started by disabling the "auto-update tags from the internet", but that still means I have to hand-edit all of the non-classical files to delete the composer tags. Not only does that take a lot of time and upkeep, but it does delete information, which may be useful?
So my suggestion is, could you restrict the inclusion of Composers into the database to only those music files that were in a specific list of genres? Yes, again, another config file thingy. But I think we could come up with a decent list of genres to use as a default?
Does anyone have a better suggestion that doesn't involve editing the tags?
