I play my PCE CD's in my PCE all the time. The Data track will usually, stop after awhile or continue playing, for the duration of the recording. However I only play it in my PCE.
Just do not load the disc into a non-pce machine, for the love of gosh........ I mean seriously, one time I inserted a game disc into my computer and the disc cracked after awhile. Also regular CD players might be dirty from the pop music being played.
