This sample/digest tape was freely distributed via Shinseido (新星堂) shops, some time in 1997 (after the band's major debut and presumably after the release of the first single which was released in April of 1997, but before July of 1997). For that reason, I presume that the release month was around May of 1997.

As for the contents, the songs present all consist of snippets until the first chorus (as is evident from the track times). Sides A and B are identical in content.
