iTunes Music Store: Made in iTunes Section [Updated]
It appears that Apple is adding them country by country. As of the start of Tuesday June 20 (midnight Pacific time), 11 of the 21 stores showed the new section in the bottom right corner of the home page. So far, the section is empty in all stores, with only its heading showing.
The section title is "Fatto da iTunes" for Italy, "Hecho en iTunes" for Spain, and "Made in iTunes" (English) for all other stores.
Countries with the new section as of the time of this posting: Belgium, Denmark, Finland, Greece, Italy, The Netherlands, Norway, Portugal, Spain, Sweden, Switzerland.
Countries without a Made in iTunes section: Australia, Austria, Canada, France, Germany, Ireland, Japan, Luxembourg, UK, and USA.[Update] Apple has removed the Made in iTunes section from the iTunes Music Store for all countries, leaving no visible evidence of the unexplained additions last night.
