This week, as expected, the most popular song in America is Lionel Richie's "Say You, Say Me," which was destined to be No. 1 as soon as it was released from the soundtrack of the movie "White Nights.
One song to watch next week is Eddie Murphy's "Party All the Time," which moved to No. 3 from No. 4 and has an outside shot at No. 1. But the real threat comes from "That's What Friends Are For," a song recorded by Dionne Warwick and Friends (including Stevie Wonder and Elton John) to raise funds for AIDS research. This week, "Friends" jumped to No. 8 from No. 14 among pop singles, to No. 6 from No. 11 on the black charts and is already No. 2 on the adult contemporary list, where "Say You, Say Me" is in danger of losing its No. 1 ranking after three weeks at the top.
