I use a portable CD player at work and at home in bed. It's an Insignia, which is the Best Buy brand.
This player will play all my home-burned/blank CDR's without labels. It will NOT play any sticky-label type CDR's, or most commercially manufactured CDR's with the "silk screen/solid enamel" type label surface, which is really surprising. Almost all CDR's made by Kunaki will not play on it.
This morning I tried playing the new AWM disc (which has the silk screen/solid enamel type surface) and it wouldn't play, but it WOULD play my Thom Brennan "Mountains" CDR, which seems to have the exact same type of surface.
By the way, all these CDR's play perfectly on my Sony 5-disc changer for my home system, and in my car's CD player.
Any idea what could cause these not to play on the portable? I'm probably going to get another portable, but I am curious nonetheless.
