I'm sure I've blogged about the much anticipated media player Songbird before, but it has been awhile since I've heard anything about it. Well, take a look at how this brilliantly featured media player has matured:
Also noteworthy is a new media player called Jajuk. My favouritest ever media player so far is Amarok (unfortunately, only for Linux at the moment) - but Jajuk comes very close. It features an extensive amount of features - Wikipedia support, super smart playlists, various ambiance options, tags, keyboard shortcuts; the list goes on and on. Seriously, give it a go and see for yourself.
(both are free, of course).
