how bizarre. i burnt my copy-protected zero 7 cd to my computer ages ago, when i bought it. and then realised that for some reason, the cd refused to play on my discman. and it's not one of those ancient discmans that have trouble playing various things. it's barely a year old, it can play mp3 cds etc. however, i had copied the cd to my hard drive before ever trying to play it on my discman, so i surmised that that could be the problem. however today i decided to burn the songs to a cd-r, and try that out. and it works on my discman. ironic isn't it, to have to copy a copy-protected original cd to be able to play it. i should try the original on some other non-computer cd player sometime and see if it works. technology is such a peculiarly messed-up thing.
