You can choose to sort your playlists by Name (the default) or by # (the number of tracks in the playlist).

You can tap any playlist to go into it.

When you are in the playlist track list you can tap any of the column headers (Name, Time (track length), Artist, Genre, BPM, or Comments).  Tapping on a track will open the track and begin playing it.
