music came second with 15%, and traditional Finnish “iskelmä” music,
reggae, pop, rock, classical, and acoustic music were also mentioned.
Interestingly, two persons associated the picture with pornography and
homosexuality. 18% of the participants commented that they associate
saunas with silence, i.e., no music should be played in that context.
Most participants (60%) associated the “Sports event” picture with
rock music. Other terms that were mentioned included pop, hip-hop and
rap music, positive, happy, party music, music played in sports games,
organ music, and live music. The songs “We Are the Champions” and
“Eye of the Tiger” were mentioned several times.
After using the prototype at home, users were also asked to rate how
well the mood pictures matched with the recommended music on a seven-
point scale (1=did not match at all, 4= neutral, 7=perfect match). As
shown in Fig. 11.12, the medians were close to neutral; there was quite a
lot of variation in the grades. While most mood pictures evoked similar
types of feelings in the participants, participants preferred to listen to
different types of music in such moods and contexts. In other words, while
one person may associate a picture of a concert with rock music because
he/she loves to go to rock concerts, the other person may hate such music
and thus will never have such an association. Also, the preferences of the
participants did not always match with the preferences of the authors (i.e.,
persons who selected the seed songs for the prototype). Thus, one can
conclude that it is extremely hard (or even impossible) to find such mood
picture/seed song pairs to please every user.
