A new name for the soft rock, easy-listening sounds of 70's and 80's music that is characterized by it's earnest, treacly male lead singers who apparently have removed their genitalia in order to tap into their feminine sides and, ironically, appeal more to their female paramours.
To qualify as being "Eunuch Rock", the band must have a male lead singer and can sometimes, but not always, feature an acoustic guitar, twinkling piano or saxophone solo.
Definitive examples of Eunuch Rock are: Stephen Bishop (of Tootsie fame), Ambrosia, Air Supply, Player, Christopher Cross or anyone who sings in a falsetto.
