The PPL Repertoire Database displays data from a wide variety of sources and PPL continues to make positive steps to improve data quality.
These steps include obligations that PPL now places on its rightsholder members to provide performer line-up information (see here for more information), together with repertoire investigations carried out by PPL staff and music experts.
Further to this, PPL encourages its performer members to actively claim for their performances to ensure that their contributions are captured and revenues allocated accordingly. These claims may require supporting evidence, depending on value threshold and the roles being claimed.
