Effects of the listening context on responses to music largely have been ne
glected despite the prevalence of music listening in our everyday lives. Th
is article reports 2 studies in which participants chose music of high or l
ow arousal potential during (Experiment 1) or immediately after (Experiment
2) exercise or relaxation. In Experiment I, participants preferred appropr
iate arousal-polarizing music over arousal-moderating music. In Experiment
2, participants preferred arousal-moderating music over arousal-polarizing
music, such that their listening times contrasted clearly with those in the
first study even though the same music and methods were used. Thus musical
preferences interact with the listening situation, and participants' music
selections represent an attempt to optimize their responses to that situat
ion. When motivated to maintain a state of polarized arousal, listeners use
music to achieve this; when they have no such goal, they use music to mode
rate arousal.
