Readers, Just learned an interesting observation: navigated to a directory containing some audio files (mp3, ogg, etc.)
Activated the command: wget -r -A *.mp3 http://url/to/mp3/files After download completed, some the majority mp3 files became empty directories, but curiously a minor few (estimate 10 %) remained as audio files: ls showed audio1.mp3 became audio1.mp3/ The moral, be careful fellow novices! :)
