A few years ago, my roommate and I decided to set our alarm clocks to super-grandiose classical music, rather than the pop song radio wake-up calls (or free ringtones) we had been using. This worked great. Waking up to trumpet fanfares on top volume made me want to float out of bed and conquer the world.
I’d like to see an alarm clock that does that. Of course, I have plenty of other gripes about alarm clock interface complexity, but for now, let’s just say the only songs it can wake you up to actually make you want to get up.
