Odd behaviour of progressbar and playlist

[Spielmops]

My playlist is built from a folder on extern SD-card, which ist FAT32-formatted. Half of the items appear like this: "Atlantis Shadows" The other half: "Aquarius - Hair.mp3 " If I play the first one, then everything is as expected, the runtime is shown and I can forward and rewind with the progressbar-button. If I play the latter, no runtime is shown and I can not fast forward or rewind the music.

Every file is encoded the same way with metadatas filled and I can not find any difference between the first and the second kind. And I avoid any special characters in any filename like German umlauts and others (old behaviour since home-computer-times). My computer, with which I "make" the files, is an up-to-date Linux-machine set to UFT-8 characters. Every file is coded as MP3 with 128-bit, 44100 kHz.

In the attached screenshot there are three files of the odd-kind-type on the left and three of the normal-type on the right side.

What could be the reason for such behaviour?

well Im fetching the things from the devices MediaStore, so maybe the fields are corrupt there. Are you copying all files to your mobile the same way? Do all files play well in other apps?

[Spielmops]

I have "musicplayer for pad/phone" and all is very well. All titles show the same style, Metadatas are shown and every file can be fast forwarded/backwarded without problems.

The file come per smb (Totalcommander), per Bluetooth, per "transfer files" via USB and by copying to the sdcard. As allready mentioned: all files come from the same machine and are created by Audacity since years. How can I get the mediascanner to forget everything and scan anew?

try renaming the files maybe

I tried it with one file: works. But I will not rename 2000 files ...
