looking for someone who knows the Resident Evil OST soundtracks well

I have a few questions to any RE fan out there that may have the answer. I’m looking to get the Resident Evil 5 and 6 OST but I am unsure which are the best versions. I know some versions are compiled differently and have more content. I know on some sites where you can purchase them, it looks like the RE 5 and RE6 OST’s are just under 3 hours in length. Can anyone vouch for these?

I’m also guessing that RE 5 3-disc version doesn’t include the DLC stories, so that makes a difference too.

I really love video game soundtracks and Resident Evil is probably my favorite video game series. Why I’ve waited this long to start collecting them, I don’t know, but I wish I did.

I have also heard great things about the Code Veronica X OST as well as the Darkside Chronicles OST.

I left something else out too. I do think it’s a terrible crime that they don’t just release these soundtracks in their entirety with a good arrangement, 75% of the video game OST I get only have about half of the score or less.

So regarding the question above, I guess I’m looking for versions that don’t necessarily include every little theme/song, but something that does for the most part include most of the musics from the games. Overall flow from one song to the next is important to me as well, it’s easier for me to appreciate that way.
