As I opened up my new copy of R.E.M.'s compilation Part Lies ... I found myself bemoaning current state of CD packaging and thinking about changes throughout the years. Any help piecing together a timeline would be much appreciated. Was there a specific time when the bulk of jewel cases went from a black strip along the edge to a clear one, or was this a gradual change? When did the cardboard sleeve style of packaging first take hold? I feel like I remember a time in the early 00's when some albums were released in both a cardboard sleeve AND a jewel case. Is this correct? When did trays in deluxe editions start to be replaced by cardboard sleeves? And finally, did hinges and spokes always break or have they gotten cheaper? Thanks for any and all feedback!
