Bin/cue burning mistake, or corrupted file?

I have a Saturn bin/cue file, say, Shining Force III, Scenario 1 for example. I burned it on using Nero (and yes, I know how to use Nero to burn bin/cue CD images).

The end result is two separate tracks, a data one and an audio one.

The audio track plays back as a bunch of high-pitched garbles on my computer, and, I'll be honest, I don't own any REAL Saturn games (I downloaded scenarios 2 and 3 because it is quite impossible to find, and plan to borrow a friend's Saturn to play it on), is the audio track SUPPOSE to be all garbled, or is it the result of a corrupted .bin file? Or some other cause? Please help me out, thanks.
I don't know if this is true for this particular game, but what came out as audio may be supposed to be a second data track... Have you tried BINchunking the image and burning it as iso/cue? (Does BINchunker produce two data tracks?)
