I have an iPod Touch. I have a few (a lot) of playlists. Does the shuffle algorithm remove songs longer than say 15 minutes? I have this playlist for when I get a 90 minute massage. I hate their music so I bring my own. I’ve been doing this for years. I have about 10 pieces in this playlist than exceed 15 minutes. These are NEVER played. I even saw the second song up on the playlist was a classical piece 41 minutes. Sure enough iPod bypassed it. Is there a command somewhere that filters shuffle settings?
