Gtkpod is a very practical tool for those users that use a Linux distribution and have an iPod to listen to music, due to the fact that there isn't a version of iTunes for this platform.
Manage Apple's portable player on Linux
It's a manager that has been developed to administrate the contents of our portable player, including a very intuitive interface, from which not only will we be able to send songs, we'll also be able to copy photos and videos.
The program also allows us to add tracks in MP3, AAC and M4A format, edit ID3 tags (that contain all the information about each of the songs, search for duplicate files, normalize the volume of each song and change the cover of each of the albums stored on our iPod. It also offers support to be able to copy podcasts.
It includes a practical mode in which we'll be able to create customized playlists without having to have our iPod connected, to be able to synchronize them later.
