Galbadia only host's the album so they wouldn't have the other un released songs.
I don't remember actually hearing Green sleaves in Killer 7 other than Garcian's whistling.

Also there was in the rip, a variation of the music that is played in the streets of Santo Domingo, but with some bongos in the background.

Yeah I also have another variation of that song.
It's the one that you hear during one of the early K7 trailers.
(The ones that had Sundance in the video.)
I also have another song that kinda sounds like some gangsta rap track.
You hear a lot of loud sirens & ish in the background.

speaking of which, here's some more ILL ass mp3's that I extracted from FSR.
I still abide by my opinion that Flower, Sun & Rain has the best soundtrack.
Much better than Killer 7's. (Although K7 had a stellar soundtrack as well.)

This is a pretty catchy guitar based song that you hear when you try to solve Tokio Morishima's codes.

This is yet another remix of the FSR theme song.
By far the best & most dramatic version of the track.
I love the last minute of this track.
(It starts out with a piano melody & then breaks down into a hardcore hip hop beat.)
This song only plays once when you reunite Natsuko with the fat salary man at the FSR theater.

The male equivalent of "Without chewing gum syrup"

A lounge/trip hop remix of the Silver Case theme song. The last minute of this song also rocks.

A stressful sounding remix of Crescent.

http://www.killer7.3dactionplanet.gamespy.com/FSR~crescent.mp3
The original Crescent song.
The best version of this song is called Crescent (Bluemoonmix)
Which can be found here

http://www.killer7.3dactionplanet.gamespy.com/SousaFSRmix.mp3
This a FSR remix of Sousa from Silver Case. (Sousa means investigation.)
The original was alteady tight, the remix is even better.

http://www.killer7.3dactionplanet.gamespy.com/FSR~lulabymix.mp3
A music box version of the FSR theme.

A song that plays when Remy is investigating the shelter children factory at Lospass resort.
