Query: Dual Disc--Be Careful

I bought the dual disc this morning, but when I got it home, it wouldn't play on my computer or in the cd player. There's a small print warning on the back of the CD they pointed out to me in the store when I returned it that says the audio side of the CD will not play on all CD players.So, be careful buying the dual-disc--I had to exchange it for the one-sided CD.Otherwise, it's a great album.
