Music streaming and playlisting activity from music streaming service.

This dataset is taken from the portuguese music social network "Palco Principal", that gathers non-mainstream musicians with fans. The website allows free music streaming and users can organize their favorite music tracks in personal playlists. The dataset consists of three files. Two of them are music streaming logs (one line per play), and one file is a music track playlisting log (users adding music tracks to their personal playlist).
