"Kool Thing" is a song by American rock band Sonic Youth, released in June 1990 in the United States (as a promotional single) and September 1990 in Europe, as the first single from their sixth studio albumGoo. The song was inspired by an interview bassist/singer Kim Gordon conducted with LL Cool J for Spin.[3][4] Although he is never mentioned by name, the song's lyrics contain several references to LL Cool J. Gordon's lyrics make reference to several of the rapper's works, including the single "I Can't Live Without My Radio" and the album Walking with a Panther. She also repeats the line "I don't think so", which appears in LL Cool J's "Going Back to Cali". Chuck D also contributed spoken vocals to the song.
