Bob Chen asks for "happy" or "get well" music, and I have a suggestion.
Try the J. S. Bach Keyboard Concerto in A major.  I've been teaching it
this semester to one of my more musical majors, working on it with her
keeps me smiling for hours after the lesson is over.  It sounds very trite,
and I wish I could think of a more sophisticated way of putting it, but
right now this concerto is quite simply the happiest, sunniest piece I
know.

DPHorn, feeling better just thinking about it.
