All of the extended tags listed in mp3tag, are these a 'Standard' common in ID3 tagging?
I've been around ID3 tagging since it started, but I've never bothered to use any applications to tag my songs. I just fiddled around in the past using Winamp, and EasyTag in Linux was all, never really doing much, just adding in a few simple fields to the songs, like, albums, artists, tracks, etc...
Now that I've started using mp3tag I noticed a big list of extended tags. When I was playing with tagscanner I noticed that program did not list all of these extended tags, so I wrote to the developer of that program asking why, or why it won't at least show them so you can change or remove them.
So is this a common standard amongst ID3 tagging all of these extended tags, or are some of these just exclusive to mp3tag, and if someone where to play with other tag editors might they find other extended tags as well in those applications also?
