Well, unlike AIWFCIY Thriller only reenters some years, when Halloween is in the middle of the week. Halloween being in the middle of the week allows for all of the activity to fall within the tracking week.

AIWFCIY on the other hand can be found charting as soon as all the radios start bombarding everyone with Christmas music and can be seen charting from Thanksgiving until the end of the year. It even reached a new peak last year.
