"Bang Bang" is a classic example of what an iconic scene can do for a song. "Bang Bang" was originally recorded by Cher and became a hit for her in the '60s. The song proved so popular that Cher turned it into a hit again in 1987. However, Nancy Sinatra's much more melancholy cover didn't fare nearly as well and was totally forgotten.
Sinatra's version found a second life in 2003 when Quentin Tarantino—who has a knack for plucking music from obscurity—aptly placed it in the opening scene of Kill Bill: Vol. 1. The song gained so much popularity that rappers like Kardinal Offishall and Young Buck proceeded to sample it, no doubt inspired by Tarantino.
