Dualdisc was first rolled out in 2004, so that means they have pretty much constant contact with the rest of the world (Presuming, of course, that the makers didn't just bollocks up with continuity, but given that all the other music aside from Hurley's CD player have explicitly been on old-style Vinyl records, I doubt they did).
I think people are reading too much into this and it could be a minor boo-boo on the producers' part in regards to what type of disc she puts in the CD player to listen too.
