I apologize if I missed a step or did not do something on my part. Thank you for the data and all the examples.

The training using cnn after pre-processing the audio files starts off but as soon as some files are fetched, the training stops with the below error:
Unknown: CalledProcessError: Command '['ffmpeg', '-i', 'path-to-dataset\\fma_small\\099\\**099134**.mp3', '-f', 's16le', '-acodec', 'pcm_s16le', '-ac', '1', '-']' return ed non-zero exit status 1.

Looking at this, I checked the file 099134 and my default audio player could not play it and also the metadata(in File explorer) for that file seems to be missing as shown below
