Javier Ramirez has introduced Wakefy for macOS 10.12 or later. It’s a free app that turns your Mac into a Spotify alarm clock.
Wakefy forces you to actually get up and walk to turn off the alarm, and allows you to wake up to your favorite Spotify tunes. It works even if your Mac isn’t awake. The utility lives in your menu bar and only pops up when you need it. You can set it once, then forget about it.
