Hi can anyone explain why MP3Tag shows BPM files as follows for ALAC/m4a files:
BPM tagged by Mixed in Key, Rekordbox etc. = 125 or 125.50 // but MP3Tag shows the same BPM value as: 00125 BPM
It does not seem to be an issue as Rekordbox reads the BPM as a normal BPM value but it did take me hours of troubleshooting to figure out that MP3Tag was the cause of the confusion for me. This was most likely my lack of knowledge about ALAC files as I converted my library from from FLAC to ALAC this weekend, and I have little previous experience with ALAC files with MP3Tag.

If I clear the bpm tag, it stays empty. When I put the same track into serato dj to play the video, the track renders just as 98....I'm not entirely sure what the issue is. All my audio mp3's disp…
