Since CDs are cheap to make and the master can be stored on computer media, I doubt many CDs will ever become "valuable". A friend had a very valuable Laserdisc collection; all special editions and collectors editions. They DVDs came out and the laserdisc became almost worthless overnight.
Japanese reissue CD question
I had the high bid on eBay for a Japanese CD of Metallica "Black Album" I got it for $26 and its described as in excellent shape.It has a bonus track on it.I know a bit about the sound quality of Japanese LPs's as I have a few.My questions are: Is this a good price and is it bound to go up in value? Also,how will the sound compare to the Elektra release I already have that sounds pretty darn good already...... Thanks!
