Mood Has An Effect

I was listening to a musician playing an assortment of familiar songs, and I noticed that I was in a bad mood.

I knew that because of how I would have answered a quiz like this one:

When I hear "Singin' in the Rain", I think of
A. Gene Kelly in Singin' in the Rain.
B. Gene Kelly on The Muppet Show.
C. Malcolm McDowell in A Clockwork Orange.

When I hear "Over the Rainbow", I think of
A. Judy Garland singing it in The Wizard of Oz.
B. A wistful gay man listening to it on his stereo.
C. Judy Garland's suicide.

And like that.
