That was my point. If you want something you can play over and over for a couple of years with no loss of sound quality, CD is a good medium. If you want something that will last a much longer time and you aren't concerned about sound degredation then other mediums are better. It all depends what you are looking for. All mediums have their plusses and minuses.
We don’t need spinning discs anymore. That is 1990s technology at best.
If you take a 1 hour video clip (mp4, avi, mpg, etc) at roughly 250mb and put it to DVD so it will play on a DVD player, it suddenly takes 4GB. Same with an album’s worth of digital audio files (even in higher audio formats than mp3).
The equipment manufacturers (which also happen to own major labels) don’t want to see the market give up the “discs”.
They don’t think people would pay $200 for a chip or “cartridge” with all of the Beatles albums on it.
Plus if you scratch a disc, it can’t be resold on the used market and you may even buy the same album you already purchased.
