The correct title of this article is iPod. The initial letter is capitalized due to technical restrictions.
An iPod is a MP3 player from the 21st Century. In 5,000,000,000, a jukebox that was owned by Cassandra was thought to be an iPod. Furthermore, it was also thought that Soft Cell's Tainted Love was a traditional song, and Britney Spears' Toxic was a ballad from Earth's classical era. (DW: The End of the World)
