RPM was a Canadian magazine that published the best-performing singles of Canada from 1964 to 2000. Thirty-two songs peaked at number one this year, starting with "Do They Know It's Christmas?" by Band Aid and ending with "Say You, Say Me" by Lionel Richie. Not counting the number-one single from the magazine's first issue, "Do They Know It's Christmas?" was the first song to debut at number one on the RPM Singles Chart. Excluding the musical acts composing Band Aid, Northern Lights, and USA for Africa, 19 different artists reached the top spot for the first time in 1985.
