Detailed Display
On the album view page, any DiscIDs are shown at the bottom of the page, and clicking on these or on the "View Info" link will give a detailed display of the DiscID.
DiscID Clashes
An album may have any number of DiscIDs, and a DiscID may be linked to multiple albums. This is because DiscIDCalculation is involves a hash of the frame offsets of the CD tracks.
Different pressing of a CD often have slightly different frame offsets, and hence different DiscIDs.
Conversely, two different CDs may happen to have exactly the same set of frame offsets and hence the same DiscID.
