Can I download from iTunes / system updates whilst my MacBook Pro is sleeping?

[MisterBigMack]

Is there a way around this. I wish to download a lot of my music from iCloud , like 40gb worth but I don't want to keep the MacBook "awake" does it download when it's sleeping?
The same with system and app updates, it seems to stop when it goes to sleep, is there a way around this?

Because the download is so big I will have to leave it open and turn the energy setting off so it doesn't go to the auto sleep

Help please!

No and yes.

If running Lion or later, and on certain hardware, can turn on Power Nap which allows software updates, but doesn't do music downloads.
