Jamendo-C

In the previous release, we included only Jamendo-A (N = 2,559; all tracks selected through k-means clustering-based sampling) and Jamendo-B (N = 1,119; tracks unanimously rated as <emotionally-conveying> by all three raters). We released Jamendo-A because the estimated means and confidence intervals based on online ratings of a subset of 100 tracks suggested that Jamendo-A was more liked by larger population.

However, we overlooked the fact that some tracks had been flagged as undesirable for reasons unrelated to emotional or subjective evaluations. Specifically, 65 tracks in Jamendo-A were flagged as <copyrighted_content> or <explicit_content>. Because the original release of MTG-Jamendo did not involve human screening for such issues, there may be additional tracks in the original dataset that fall into these categories.

To minimise the risk of encountering potentially problematic content in human experiments, we have released a new set, Jamendo-C (N = 2,494), excluding these 65 tracks (Zenodo v2).
