There has to be a way to measure power usage while running programs though. I still think it would be useful info for everyone to know which music apps will give you the best battery life.

i hear you, but to obsess over something so petty..... measuring the power usage of each, and every app to save what, 5 mins of battery time? for 14 bucks you'll won't care about all all of that, because you'll have enough juice to listen to music/watch movies non stop for two days straight... trust me, take advantage of that battery door, and leave the app power measurements to those who are less fortunate (iphone users). *two cents*
