Hunting for Three OSTs

I just recently got into the "Jojo’s Bizarre Adventures" series, and actually like the music. I have the ones on GH’s page, but I found out that they had three CDs total, so I don’t know which one Galbaldia has up.

These are the CD titles that I found through searches:

JoJo No Kimyou Na Bouken Original Soundtrack
JoJo No Kimyou Na Bouken Original Soundtrack Vol 2
JoJo No Kimyou Na Bouken Original Soundtrack Vol 3

Perhaps some help here? ^^;

Say, I’m a pretty big fan of the Jojo’s Bizarre Adventures series, and yeah, the music on the game is pretty cool.

But I think the one on GH is the ST for the anime. I’m still not sure :/
