VGMIDI is a dataset of 200 MIDI labelled piano pieces and 3,850 non-labelled ones, all piano arrangements of video game soundtracks. Each piece was annotated by 30 human subjects according to a valence-arousal (dimensional) model of emotion. The sentiment of each piece was then extracted by summarizing the 30 annotations and mapping the valence axis to sentiment. The dataset is available on github.
