Platte et al. (2013) reported that healthy participants exposed to
negative mood-inducing video clips rated quinine sulphate to be
more bitter than when exposed to a positive video clip. The video
clip was used to induce mood, and it is possible that in our study
music could have also evoked different mood states. It would also
seem that the lowered ratings for disliked music might be due to
increased arousal by the negative valence of disliked music, as
postulated by Gomez and Danuser (2004) and Bradley and Lang
(2000). Thus, the changes in taste perception in our study may
potentially be explained by the induction of a negative mood state
when listening to disliked music
