They all include roughly the same set of features such as support for audio file types and digital audio players, including the iPods. They retrieve album, submit played track information to Last.fm, and supports podcasts. With such software, look and feel are all important, so I have included screenshots and links to the homepages of each. Since they are all free why not audition them all and find the one that best suits your requirements.
Personally, I prefer a more svelte audio player like Winamp. Since there is no native Linux version of that, I use Audacious, which supports some Winamp skins. That is probably just as well because the default skins are not great.
More Linux applications soon.
