I really liked the convenience of being able to right-click an mp3 for a quick edit of tags (e.g., ranking). I used dbPoweramp for this. See the attachment for a view of its simplicity.
I recently discovered dbPoweramp has the nasty habit of erasing tag entries in PodcastURL (WFED) and PodcastCategory (TCAT). See /t/17085/1. I need a replacement.
I request something akin to the tag panel (CTL+Q) in Mp3tag, but one where tags can be easily edited for each mp3.
