Ok, this is just a random thought, but I think it would be a nice addition to the site..
If it's possible to make an index of crc32 values of each track, the audio tracks can be marked with a green flag or a green V or something like that if the track exists in other dumps..
If you move the cursor over a track it already lights up... maybe it's possible without too much work to link to a new page that has a list of all games that include this track (or perhaps all tracks with the same size in bytes to identify possible bad dumps with cut off data)?
A lot of games share audio tracks, so this would be a nice way for us to verify that a dump is correct by comparing them to other games.
