Another plugin for iTunes....
1)Aurora is a free Alarm Clock for your Mac that lets you wake up to your favorite iTunes or iPod playlist or any TV or radio channel from EyeTV.
2)There is also "Awaken" that does the same:
3)for PC users a good app is iSnooze
A big plus is being able to use the apple remote to control the alarm (shut off/snooze).
Either way I was tired of that stupid standard alarm clock sound and tried Aurora out and works like a charm!
