What Year Is It (#87)?

Clues:

A great time for AM radio. These songs were all in the year-end Top 25. “Paint it Black,” the Stones; Jimmy Ruffin’s “What Becomes of the Brokenhearted,”; “You Can’t Hurry Love,” the Supremes; “Reach Out,” Four Tops; Percy Sledge’s “When a Man Loves a Woman,”; “California Dreamin’,” the Mamas & Papas; and The Beatles’ “We Can Work it Out.”
