Support for audio players running Rockbox.
These are typically mass-storage accessible, and appear the same as the devices running the default firmware. e.g. an iPod running Rockbox will look like an iPod. Detection could be by looking for /.rockbox in the root of the player.
- File layout; files should be placed in /Music/Album/Artist
- Metadata; Rockbox has something called the Tag Cache, http://www.rockbox.org/twiki/bin/view/Main/TagCache. The database format is not stable, but there is a plain-text export/import functionality. We should write to /.rockbox/tagcache_changelog.txt when writing files to the device.
