magister said All very good advice from PB. I don't think that trying a barcode has ever worked for me, whether for SACDs or for Redbook CDs...It can be made to work, because in other systems it does work. My DMP recognises very few CD, I was surprised it didn't even recognise The One SACD being sold by PS Audio! (by that I mean, no coverart).
In my Kaleidescape system it recognises most CD on import (the PS3 is even better). If a CD is not recognised just enter the UPC of the disc and in a few days the missing information has been updated to the music db.
