  In the present study, we address the relationship between the emotions
perceived in pop and rock music (mainly in Euro-American styles with English
lyrics) and the language spoken by the listener. Our goal is to understand the
influence of lyrics comprehension on the perception of emotions and use this
information to improve Music Emotion Recognition (MER) models. Two main
research questions are addressed: 1. Are there differences and similarities
between the emotions perceived in pop/rock music by listeners raised with
different mother tongues? 2. Do personal characteristics have an influence on
the perceived emotions for listeners of a given language? Personal
characteristics include the listeners' general demographics, familiarity and
preference for the fragments, and music sophistication. Our hypothesis is that
inter-rater agreement (as defined by Krippendorff's alpha coefficient) from
subjects is directly influenced by the comprehension of lyrics.
