thanks to @ashen latch changing the <> to != helped me get the original program back on its feet and following the advice from the cmd I managed to get this far with it:
C:\Users\X\makechannelradio.py:38: SyntaxWarning: invalid escape sequence '\m'
search_path = 'd:\music'
searching d:\music for media files...
d:\music\folder1\music1.flac
error (with getLength()?)
d:\music\folder2\music2.flac
error (with getLength()?)
0 files found
I have ffmpeg version 2025-12-31-git-38e89fe502-full_build-www.gyan.dev
