usage

audioplayer.exe "path to file or folder"
if a file or path is specified the folder will be scanned for an audio file
if the folder has subfolder(s) these will be scanned for audio files as well.

generate .m3u: audioplayer "path to file or folder" "tag" "tagquery"
example: audioplayer.exe g:\data\mp3\classic artist beethoven
generates the m3u file beethoven.m3u
which then can be played by audioplayer.exe beethoven.m3u
