so i want to play audio while i sleep at night. and i want to ensure that i am using less power. what option is the best? sleep? hibernate? stand by? please tell me. i want to keep the audio playing but i want to turn the computer off at the same time. is it possible? if so how? and if its not possible, how can i ensure that all the applications that im running before i make the computer inactive stay on? thats my big concern. i dont want to lose tabs and everything when i leave it on sleep mode/hibernate/stand by or whatever.
