When users having _ in front of Filenames. Centova is not showing Track Details overall.

Reproduce:
- Uload an .mp3 with some Filename. But put_ in front of Filename. (Example: _Where Do You Go .mp3)
- Create an new Playlist with this Title
- Start Server

System:
Centova Cast 3.2.4

Maybe someone should test it is affecting actual Centova Versions.
