Thanks Peke! I did a rescan and now the BPM values are displayed.
The option "scan continuously" was enabled, so I did not realise that a rescan was necessary.

Once again, the "problem" is related to my setup: the db and files are located on a network share while MMW is running in a VM.
Changes in foobar (same VM) did not trigger events so that MMW did not recognise the changes.

I guess it's time for me to checkout MMS and MMW5 as I guess that combination should fix my little "issues" with MMW running in the VM.

Hi,
Can you please supply DL link in PM to one sample file so that I can analyze?

Have you re-scanned into library and checked if using My computer tree node reads it?

I used Foobar with it's BPM Analyzer Addon to add BPM values to some mp3-tags.
MMW does not recognize these BPM values in the "Properties->Details" view of the songs.
Windows Explorer shows the BPM value correctly in the "Properties->Details" view.

MMW 4.1.24.1883 portable
