In playlists created by users, you do not search for the part you like. The time you searched for, the name of the song, and the name of the singer are displayed if the name or description of the playlist, but not in the playlist. what does it mean? Its radio algorithm means that a program that is already bad can not reach the list of users who have added the list of tracks you like. I think it is a very important minus. You have to listen to the popular one.
