KISS was mostly a "watch/experience" group -- the only "listen" cut was "I wanna Rock and Roll all night."
I'd add "Detroit, Rock City" and "Beth" from the Destroyer album.
Speaking of "Detroit, Rock City" and "Beth", KISS performed both on The Paul Lynde Hallowe'en Special in 1976, probably as an album promotion.

KISS at 25:40. Florence Henderson singing "That Old Black Magic" at 39:00, then KISS again. Paul Lynde's attempt at humor after "Beth" is painful.
Watch it all, if you dare!
