iTunes Alarm Clock is an alarm clock application that will interface with iTunes and allow you to choose any song in your iTunes library to play at a certain time. iTunes Alarm Clock has been released, this completely rewritten update addes multiple alarms, recurring alarms, customizable alarm messages, an improved user interface, an improved song selection dialog, and more. I am no longer the sole author of this software, Geoff Basore assisted me on this project. Also because of the redesign, the program can now be made cross platform

This functions quite well as an alarm clock hence its name. Since the program invokes iTunes/Quicktime to play the music directly, even DRM songs from the iTunes music store will play without problems.
However do not worry if you do not have iTunes, iTunes Alarm Clock can play Mp3 files directly, in which case it will use Windows Media to play the file.

The license of this software is Freeware, you can free download and free use this digital clock & timer software.
