I just downloaded Songbird, a new media player that’s under development (0.4 currently). Songbird is based on Mozilla technology.
One of the cool things about Songbird is that it’s both a music player and web browser. If you load a web page that contains links to mp3 files, it offers to download them into the player for you.
Here’s a shot of Songbird showing the KEXP Blog:
Songbird also support iPods, though I haven’t tried that yet.
