Because of this, "American Top 40" switched to the Hot 100 Airplay chart (then known as the Top 40 Radio Monitor). These songs generally scored much higher radio airplay, and some were not even released as singles (such as "Steel Bars" by Michael Bolton). During this time, a few songs made very high debuts, including two that almost debuted in the #1 spot: "I'll Be There" by Mariah Carey, which entered at #4, and "Erotica" by Madonna, which entered at #2.
