play music form library with timer or alarm-clock

I am looking for a way to automatically play random music from a playlist in Music-app at specific times and intervals.

I Had such an app, but since Sonoma and later this does not work anymore.

I am looking for a work-around with the alarmklok (without alarmsounds!) or via another app.

Preferably it will work when the Mac is in sleep-position.

I found a way on the iPhone to do this and link with the speakers, but this is not working well and the alarmsounds keep working.

So is there anyone with suggestions?
