Music and sound control for alarm

Would it be possible to add an option to the alarm sounds to use our own downloaded songs/ sounds? I have music downloaded that I use for the Apple alarm clock right now.

Also to go along with that, it would be really cool if the app could have the option to have the beginning part of the alarm/ song start at a low volume and gradually get louder till a set volume so you have a more relaxed, but still loud, wake up, rather than it being jarring.

Really cool app, thanks!
