some time has passed since my helpers went offline due to my new website. Sorry for this.
But now I put the stuff online again and also included the sources.
You can get some information and download it here:http://www.troelfdesign.com/en/downloads/monkey-tools/
The four packaged tools are:
Play Date Manager, Advanced Rating, M3U2SPL converter and a new one: Rockbox Stats Importer.
