Well, as I already explained, an audio cd is made
of multiple tracks (not sure if that means multiple
sessions). You cannot dd it that way. To wit:
$ dd if=/dev/sr0 of=sr0.dd
dd: reading `/dev/sr0': Input/output error
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00558614 s, 0.0 kB/s

Compare that with the fedora 17 DVD:
$ dd if=/dev/sr0 of=sr0.dd bs=2k count=10
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 3.55596 s, 5.8 kB/s
