When you select a Playlist to make available off line how do you know when it has finished downloaded all the songs? With Beats each song got a red dot in the top right of each song as it downloaded and it would say ‘Downloading 15 of 25” so you would know when they were all downloaded. I see the little iPhone icon appears in the upper right but what about each song in the list. They have a spot for this and if you download individually it appears but not in a Playlist download. How do you know when all the songs have completed the download so it is ‘safe’ to leave the WiFi spot?
