1) Playlist will be generated by parts. Each part have its length (set in Tracks quantity or Duration).
2) For each part there are filters like: comments, year, language, rating, and many others.
3) Each part can have its own source of tracks: folder, playlist, Music Library file.
That will allow to create playlists like "30 minutes of rock, then 10 minutes of pop and 2 classical tracks". Also, possible to add jingles, sweepers, etc.
Playlist Generator Pro can be called automatically from RadioBOSS's scheduler.
The first beta version will be released later today. It's almost ready. But, as a first version, not all features are enabled yet.
