Thanks for this cool little app. I am currently rummaging through my empeg constructing a playlist that starts gently but becomes very energetic within 10 minutes.

Glad you find it useful. Let me know if you run into any problems. One thing I'm not sure of is how accurate the timing is... Like, I just have a detached thread sleep for the number of seconds until the alarm should go off. It should be accurate but I wouldn't use this as your only alarm clock until you're sure it's working right.
