Ive got one of those alarm clocks that has a light on that slowly gets brighter then the alarm goes off, the thing is ive got used to it now i wake up as soon as the light comes on & you can turn it off just turn down the setting.
My gf's alarm, going off every 10 mins because she's incapable of just getting up when it goes off, meaning I lose out on the best part of an hour's sleep
Dizzy Mizz Lizzy's Silverflame has been my preferred alarm tone for ages. Danish rock band from back in the late 90's early 00's.. Starts out nice and slow, but it rarely fails to wake me up!
