Thoughts?  Prospective purchases?  Can't say there's anything I intend to pick up this month, though a few of the samples from the Sims Medieval and PixelJunked Shooter OSTs sound decent.

Not included in that list but I just got my shipment notification for my Tim Burton / Danny Elfman box set and that's about all there is worth looking forward to this month

Myth The Xenogears Orchestral Album on vinyl looks very delicious, but the price after placing a special order makes me sad.

Already bought Oto Gift on Amazon, some good tunes for a great cause.  Sakimoto's track is really lovely.  Pro tip: Order any digital album on Amazon and get a free year of their 20gb Cloud Drive service.  Very handy, especially nice if you use the official Android app.

Still curious about the SONIC ADVENTURE Original Soundtrack 20th Anniversary Edition disc.  I'll pass if it's just a Sonic Adventure "best of" album since I already have the OST.  How about a full Sonic box set instead?

Only other release that looks tempting is another Sega album, POWER DRIFT ORIGINAL SOUNDTRACK.  It's got the original arcade soundtrack, a prototype track, Saturn arrange tracks, and one bonus track.  Can't go wrong with Hiro's Sega tunes from the late 80s.

More notable releases:
SECL-962 | Rekishi Hiwa Historia Original Sound Track 2
SQEX-10244~5 | El Shaddai Ascension of the Metatron Original Soundtrack

04/21: Rockman Zero Collection Soundtrack -resonnat vie-

is this a collection of previously released material?

I'm really hoping NCSX can pull through and have their vendors still ship out copies of the Xenogears vinyl album and the FFIV CC Ultimate Pack which had the soundtrack cd in it.  Someone is selling the ultimate pack for $400 US on eBay and the soundtrack by itself for $200!  Madness!!!  No way I'm goin for that.

Couldn't have put it any better. I'm hoping on checking Power Drift some time soon. Can't get enough of his music.

I'll be getting the Space Invaders Infinity Gene OST (delayed from March to April because of the quake) and the new Rockman Zero deal.

I've been waiting for this for a long, long time. Nice job, SQEX.

That one also makes me happy.

Unrelated: I should also spring on the Sonic Colors OST at some point, too, before it's no longer available...just remind myself, I guess...
