Waking up with iTunes
Want to use iTunes as a wake up alarm? Copy the second script by David Schlosnagle found at Macosxhints and add the playlist functionality.
Then use crontab to wake up with your favorite iTunes playlist:
30 7,16 * * 1,2,3,4,5 ~/iTunesCli.sh playlist _Chill 1</dev/null 0 9 * * 6,7 ~/iTunesCli.sh playlist My\ Top\ Rated\ Songs 1</dev/null 0 10,19 * * * ~/iTunesCli.sh stop 1</dev/null
