I want a playlist generator to make a playlist with half an hour of music in the 1980's, so that he can do half an hour of music in the nineties. I would like the playlist generator to play a halfway playlist by various parameters of the year. I also want the playlist generator to play real playlists and based on bpm tags. I have set the 24-hour play list of categories I have set for 30 minutes. How do I do this?
