So, if you have tried with a dummy script, was it working or was it not working?

The clock situation is fine. There are a lot of assumptions involved
with running a php script in command line. Therefore, I'd like to ask
you again if you have tried with a dummy script like "echo
'/path/to/file.mp3'" and if the script was working in this case..
