Sleep deprivation would be a bad idea for me because sleep helps the immune system, and my immune system needs all the help it can get (because of my chronic infectious disease).
I have found however that _listening to music_ during sleep will prevent my sleeping a lot from having a depressant effect on my mood. I recommend avoiding music contain exciting or bracing passages; you don't want your sympathetic nervous system to become active during sleep.
If I learn something that I want to retain, then I don't listen to music that night, because the same process (REM sleep?) that tends to depress the mood also helps with the consolidation of new learnings and new skills.
