How is a Trending Report different from an Accounting Report?
Although both reports will show sales activity for all the music you have up through TuneCore in iTunes, your Trending report isn’t the same as your monthly accounting. Trending reports show trends but are not 100% perfect. People sometimes make a sale and then return it later, for whatever reason. People may take advantage of other programs such as “Complete My Album” which count sales differently at the end of the month than they appear during the week. Months don’t evenly divide into weeks, and iTunes accounting months don’t even match calendar months.
