I'm putting a substantial library on my phone. However, often, artwork isn't right (not the fault of MMA - they were tagged incorrectly) ... so I go correct it on the PC, and recopy the files to the phone. But there doesn't seem to be a way to tell MMA "hey, refresh the info for this folder" or even for the whole library. I've even deleted artists/albums from MMA and copied the ones with corrected artwork over, only to have it "remember" what it had before. And last -- even deleting the database file doesn't always seem to work - it's like somehow it cached the DB info somewhere.
It would be cool if we had the "clear library" feature on Android like we do on Windows. A secondary feature to refresh content for particular folders while leaving the others alone would be cool, too ... but I could get by with "clear library".
Unless someone knows of a way to do it now
