SongBird

Songbird is an open-source, cross platform, highly customizable music player.

It comes integrated with mashTape, Last.fm, Songkick and SHOUTcast Radio, and can be further improved by an ever-growing variety of themes (called ‘feathers’) and add-ons contributed by the Songbird developer community. It’s a great alternative player, but more than that, it’s also a solution for all your music related needs. You can download and organize music, browse news, photos and videos of your favorite artists while listening and get updated about upcoming concerts, all in this one application.
