Having read the reviews giving warnings about the synthesizer music, I bought this volume with great caution - see my earlier review of The Fugitive Season 2 Vol 1:Fugitive: Season Two V.1 [DVD] [Region 1] [US Import] [NTSC
I now have Season 2 Vol 2 in a sleeve which declares in small print (as described by previous reviewers) "Music has been changed for this home entertainment version" (note the omission of the word 'some', as on Season 2 Vol 1. The sleeve also has the two coupons which could be cut out to claim a set of DVDs with original audio back in 2009.
I can assure you that the discs I have in this set have the orchestral musical audio tracks on all of them. They sound to me as atmospheric as the original broadcasts and are a delight to watch.
Of course, the icing on the cake would be if Seasons 2-4 were Region 2 encoded, rather than Region 1, which these are - buyer beware on that score, you will need a player that can play Region 1.
