I added the Adult Top 40 charts to the SS . Back in 1996 Billboard divided the Adult Contemporary charts into two - the new & improved Adult Contemporary and the Adult Top 40. So it seemed logical to include both. Also added the songs' Pop Chart info - peak position.http://www107.zippyshare.com/v/5FNZt1u0/file.html
Another Whitburn oddity. In his books Joel added songs that peaked only on the Airplay and Sales Charts for songs that didn't make the Hot 100. He later dropped the Sales and started listing songs that only appeared on the Airplay charts as if they actually made the Hot 100. So for many songs, the charted positions listed are not those from the Hot 100 but rather from the Airplay charts, which is actually a sub-component of the Hot 100. The average reader probably has no idea the positions are not from the Hot 100. The song "Iris" by the Goo Goo Dolls peaked at #42 on the Hot 100 but #9 on the Airplay chart. Whitburn lists #9 in his book and nowhere does he list #42. He also cross references these positions in other genre books so it becomes a "fact".
I do not equate these two charts. Peak Pop positions given in my SS are from the Hot 100 and/or Bubbling Under charts. For those songs that peaked on the Airplay chart but didn't make the Hot 100 or Bubbling chart, the position is indicated as A12 not just 12.
