Not to clog your thread with a bunch of rambling posts, but while I do enjoy the DKC2 soundtrack, I just have to say the cost keeps me well away from this one. Well, that and the fact "Mining Melancholy" isn't on either version. I know people are probably sick of me bringing that up (again, sorry) but damn that is a HUGE blow. LOVE that freaking track.
Not to imply anyone else is Mr. Moneybags, but I honestly can't imagine spending that much on a soundtrack. My biggest purchases to date have been:
Rockcan Sound E Can: $250 (at launch through CDJapan; a special order)
Wild Arms XF Original Soundtrack: $225 (Why in the HELL did I sell my original one off in the first place? I'm a dumbass!)
Star Fox: $150 (nearly complete)
I want a copy of MIDI POWER Pro 6 Akumajo Dracula X ~Gekka no Nocturne~ (http://vgmdb.net/album/1275) which I'm guessing $150~$250 complete w/the Power Disc and all the fees for importing? Going to try and get that this year.
I guess my personal cap is $250.
But back on topic the only DKC OST I have is the jewel case American version of DKC3 because the music is still solid at this point and you're not complete breaking the damn bank at the same time.
Good luck on your search though. This is just one I can't imagine shelling out for much like the Super Mario RPG OSV. Man, I'm glad I'm not in love with that one, isn't that thing up to like $500?
