Survey question

If you, possibly, rather likely, in the near future had to spend several days in the hospital, what piece(s) of classical music (leaning toward Operas, symphonies, or other "complete" pieces of work) would you want on your iPod?

So far, in addition to my System of a Down, I'm including Orff's Carmina Burana. It's an old favorite- I'm particularly fond of Tempus es iocundum, not the O Fortuna we've all heard a few too many times.

So, if you please, respond in comments your recommendations.
