You'll be provided with a KISS song title. You will need to provide the next KISS song title (KST) that shares that first KST's initialism (sometimes thought as an acronym). The year of release of the 2nd (mystery) KST will be provided as a hint.
All original KISS songs from their 20 studio albums, the four 1978 solo albums, and the bonus songs from some of the compilation albums (such as Alive II and the 2001 Box Set).
