Waking up is hard enough, but studies show waking up to music is more effective than a traditional alarm sound.

The Daily Mail reports "Thought to be caused by an impaired transition from sleep to being awake, 'sleep inertia' as it is known has been linked to car accidents in drivers who have just woken up as their reaction times are slower."

According to an Australian study from RMIT University, "A sound that is perceived as melodic, produces less sleep inertia in comparison to a sound considered to be neutral."

Using a song to wake up is a more melodic sound than the BEEP BEEP of an alarm sound, and because of that, you should wake up more alert.
