I only had a quick look, but it seems pretty likely.
That could very well be right even though I do not have dbpoweramp open the music files were built using it.. but would that not be the case for any of the ripping software? Don’t use any of the other ripping software so unsure what they would present with win explorer.
Its late here so I going to retire for the night.
Thanks
The “ID Tag” tab in your Windows Explorer screenshot is 100% a plug-in as part of your dbPoweramp installation. I use it myself for ripping my CD library regularly. However, as you have found out already, the metadata handling is not always aligned with how mp3tag works.
As has already been suggested here, and in other threads where some are using multiple metadata editors, it is best practice to choose one and stick with it. Windows Media Player, iTunes, Foobar, EAC, dbPoweramp, and others all have different design philosophies for managing metadata. Let these other programs rip, catalog, or play your music but leave the data management up to mp3tag. It is 100% what it was built for.
Coincidently, a post showed up on the dbPA forum last night. @DTW I am assuming this was you after you figured out the relationship there?
Yes simply was not sure where the issue was coming from so thought I would ask both the tools I was using. Did not realize the influence that dbp had on the file and some of the FLAC finer points. So again thanks to all who responded.
