Hi the Kindle is not a MP3 player and main purpose is to read electronic media -
You can purchase and wirelessly download Kindle books, newspapers, magazines and blogs from the Kindle Store as well as download and read other types of non-DRM (Digital Rights Management) text-based content on your Kindle Touch. When your Kindle Touch is connected to a computer and mounted as a USB drive, you will see the main Kindle Touch folders. Here's a list of file types recognized by Kindle Touch:
Mobipocket files must have no Digital Rights Management (DRM) protection applied to readable on your Kindle Touch. If you purchased a Mobipocket file from a Mobipocket retailer, you will not be able to open the file on your Kindle Touch.
EPUB eBooks are also not supported on Kindle Touch.
You can add any of the above file types to your Kindle Touch without using the Personal Document Service to convert those files to a compatible type. If it is not listed above, conversion would be necessary to read the file on the Kindle
