One of my mp3 files has these parameters in MP3tag 2.96:
**length: 25.32** , frequency: 32000, bitrate: 32 kbit/s, codec MPEG 1 Layer II, tag: ID3v2.3 (ID3v1 ID3v2.3).
In file properties (Windows 10): **length: 6.25** (real value), Bit rate: 128 kbps.
Why the length is incorrect in MP3tag? And what's the true bitrate?
Is it bug?

I used MP3val for this files and it fixed the problem! Thanks!
Just interesting: why file properties in Windows file manager were correct?

> I saw a "bug" in duration, isn't for all my songs, but lot of them have an error in duration, like a song with his length is 19:15 in MP3Tag, and 06:25 in MP3 Player (I use VLC but other have the same duration) I tried to delete completely MP3Tag and reinstall the last build, but I have always the bug. A picture of this bug: Note: I have Windows 7 SP1 and MP3Tag v2.70 (and is the same on v2.69) Thank you for your help
or search yourself for "duration", "bit rate", "incorrect"
