I checked and found Track Zero on the MDR CD and it's probably best they hid it
No track zero on my Ash 1977 CD but it maybe something that was done on the UK version.
The hidden tracks will never rip as part of MP3 unless you use something like Exact Audio Copy which is capable of see the hidden info... Some over at La La posted this method of ripping those tracks.
very simple to rip that content with EAC
1. Highlight Track 1
2. Copy Selected Tracks Index Based
You will get 01.00 & 01.01
01.00 is the hidden content before track 1
