So... I've recently gotten into "possession" (IFYAKNOWWHATIMEANWINKWINK) of two Sonic X Japanese DVDs.
Namely the ones from the Shadow saga.
Since, they have a 5.1 audio track... I decided to rip few unreleased bgms (that mean, the ones which weren't on the official OST).
Once I get more of those DVDs... I'll rip more. Though that probably won't be happening soon, unless there's somebody else who "has" them, and he can give me the 5.1 6 channel ac3 audio track.
So there.

Anyway, here are the goods:
SANYKXBGM001.7z (http://www.mediafire.com/?l2m046ku4tiaeoh)

There's only few tracks there, and two of them are two different versions of GUN theme found on the official soundtrack.
Oh and, here's a preview of one track:

YouTube - Sonic X Unreleased BGM - Mystery of Project Shadow [GUN Theme VARIATION] (http://www.youtube.com/watch?v=XeULDxJTOFc)

It's the second variation on GUN theme.

I hope at least few people here will be interested in this.
Enjoy.

[To those people who asked me to rip some Ryuusei no Rockman music... I think I will be not able to fullfill your requests. Sorry.]

are there any music from the crappy US 4Kids version

Marvelous. Thank you sire. :)

are there any music from the crappy US 4Kids version

no chance in hell

awesome! I like gun�s themes, could you please rip that sad guitar theme which plays at the end of episode 38 (after live and learn)? I was looking for it everywhere . Thanks. :)

Where might I find the original soundtrack to go with this?

Thanks for it. In France we had the chance to have the same uncensored version as in Japan so this is the one I know...
Sorry to up this particular topic but it's the only one I've found, since "Sonic" is a very hard keyword to successfully search, so I'll add myself to ggctuk's request, and ask for any Sonic X (or even Sonic's 1st series, now that i'm thinking about it) soundtrack link: this thread is the only one I ever found (and so the only Sonic TV music I ever found)!

Look in the music section.
The only requirement is that you need to, you know, register.
But it's quick, painless and you don't have to anything more.

Here, on the other hand, is some unreleased tracks ripped by someone else.
There's more of them than what I did, so go grab it.

Thank you very much, there's even more that I hoped there!

Many many thanks, this is all super nice :D
