Cyndi Lauper provided a US Top 10 song to which 1980s movie?

The name of Cyndi Lauper's Top 10 song asked in the question is "The Goonies R Good Enough" (peaking at #10 on the Billboard Hot 100), of course, off the soundtrack to one of the most iconic movies of the 1980s, "The Goonies".

"The Goonies" was released in theaters on June 7th, 1985, one week after "The Goonies R Good Enough" entered the Top 40 of the Billboard chart. The movie featured Sean Astin, Josh Brolin, Corey Feldman, Martha Plimpton, Jeff Cohen, Kerri Green, and Ke Huy Quan, all portraying kids calling themselves the Goonies. The Goonies attempted to save their abodes from foreclosure and found an ancient treasure map that leads them on an adventure to discover the long-lost fortune of the legendary 17th-century pirate, One-Eyed Willy.

Cyndi Lauper made a brief cameo around the start of the movie singing her soundtrack song on the television. "The Goonies R Good Enough" was not fully completed until production was completed.
