I was wondering what would be the chance to see closer integration with Station Playlist (SPL) software? The ability to read the tags that SPL adds to the MP3's in your library would be very beneficial to the hundreds of people that use SPL. The track editor that comes with SPL for changing those tags is very limited compared to MP3Tag. The added ability to make mass changes to your SPL tags would save so much time.
Please press ALT+T in Mp3tag on such a SPL tagged song and show us a printscreen.
Then we can see, what kind of "closer integration" would be possible.
