This is an update to Gwen Stefani vs. Weezer vs. Lita Ford
Paul brought Aztec Camera‘s 1987 hit “Somewhere In My Heart” to my attention pointing out that it predates all of these. They all share a very similar descending vocal melody. Thanks Paul!
Aztec Camera - "Somewhere In My Heart" (1987)
Weezer - "Hash Pipe" (2001)
Gwen Stefani - "What You Waiting For?" (2004)
Lita Ford - "Kiss Me Deadly" (1988)
