1: TITLE BACK (OUT TAKE): This song was prepared for the title screen, but was left out for loading convenience. The song's soft echoing is the result of Mr. Sakimoto's consideration. He thought about the experience of returning from the ending to the title screen.
2: RETURN (EARLY TAKE): The first song made by Mr. Sakimoto. Compared with the final version, the tempo and composition are slightly different.
3: ? (OUT TAKE): Seems as if it were left as it was made. Mr. Iuchi's question: "Mi~ster Sakimoto, how were you planning to use this?"
4: FOR STAGE-? (OUT TAKE): This song was prepared for use in a stage, but as it was bright and pleasant, there was no place to use it. Under a different name, "Silvergun Spanish".
5: ORIGIN (OUT TAKE): An un-revised version that has very little difference from the final version of ORIGIN.
6: ENDING MOVIE 1/TAKE 1 (OUT TAKE): The song that is played with the voiceovers and sound effects in the first half of the ending movie. …But, due to Mr. Iuchi's misdirection, it was cut right out. This is Mr. Iuchi's defense: "I'm, I'm sorry."
7: ENDING MOVIE 1/TAKE 3 (OUT TAKE): When the sixth song was removed from the movie, Mr. Iuchi ordered a short version of THE STONE LIKE (XIGA theme). At that time, the kind-hearted Mr. Sakimoto prepared one more song. But again, Mr. Iuchi cut it out. Once again, Mr. Iuchi's defense: "I'm very, very sorry, I don't mean any harm…"

These songs were originally intended for inclusion on the RADIANT SILVERGUN SOUNDTRACK+ (on sale at a later date), but at the last minute before MIDI arrangement, it was decided to use the outtakes on a campaign CD. (In short, if you also buy the soundtrack, then you'll have the full version… ha ha ha)
