"The manual says it will have a backup alarm tone, which indicates to me that it won't be music. The Boom will be a little less slim in that it can manage it's own time as well as alarm. Hopefully it can use a standard alarm tone and when you hit snooze the music kicks in. Some of my music certainly won't wake me up!!!"

It would be good if we had a User Pref, that when you hit the Snooze bar, instaed of turning the alarm off it would just play the first preset, or any other preset selected by the pref.
