Comment 6 for bug 1085691

I mean, I'd be for adding to the Library menubar item:

-update metadata
-generate missing data
-remove deleted files
-scan for new files

OR: unifying all of the powers into one action "scan"-or-"Analyze". In other words, just selecting that button/menu item would add:

-BPM
-ID3 tags/metadata
-waveforms
-key
-presence or absence

...to Mixxx's various databases. In this case, it would also be super helpful if Mixxx could avoid redoing the work when it isn't necessary, i.e. when all the tags and waveforms are already there. Like for instance currently it isn't clear if "select all" in the analyze pane actually re-analyzes tracks that already had full data saved.
