Sometimes the track number field is missing from MP3, WMA, OGG, APE, FLAC tags. Although track numbers may be present in filenames (in which case you can always extract them using the generate tags feature of the MP3 tag editor), it is easier to fill out the field automatically.
First, select audio files. Click the "Generate tags" button on the toolbar in the "ID3 tags" area:
A new window will be shown. Make sure that the "Tags generator" tab is selected (see the screenshot below), then click this button:
In the new dialog, enter some number to begin with.
Any number can be used as the start number.
Set "Fields from tags" either to "Overwrite" or to "Overwrite only existing fields". If you select "Overwrite", please uncheck all other fields:
In the bottom part of the window, click "Generate tags" to save the newly generated track numbers.Download now!
mp3Tag is great, by the way. I am a bit of an addict when it comes to music. I download a lot of music files from blogs and many of them are poorly tagged and named. mp3Tag makes the process of making them more useful so very easy. I have hundreds of files from a time before I purchased mp3Tag and am now going through those files to fix them. I simply could not do this without mp3Tag.
Keep up the great work. I look forward to future versions.Randy
