I'm saying that this SONG is unique becuase it is mixed that way. It's on my laptop but burned off the ONE (greatest hits) album.
Also, becuase my receiver uses Dolby Digital (5.1) in DVD mode, it uses all 6 speakers with Dolby Pro Logic 1!!!! It's a really unique receiver. It's low end but that adds to some of the uniqueness.
Oops, I was thinking Dolby Surround, not PLI. I think the reason for the audio only coming from the sides is that there is bit information on the audio track that indicates that is has to be played on left and right channel, so that in certain times it can be only left or only right as it was mixed.
The Dolby PLI will will copy any sound that does not have a distinct location information to the Center and surround channels. From looking into it a bit more this seems to be the reason why.At least this is what I get from the limited information with brief research on PL1. I skipped PL1 as I went from Dolby Surround straight to Dolby Digital/PLIIx.
