A bit of old news, but in case you are still using Songbird 1.1, a newer version was released a few weeks ago. Songbird is an alternative media player powered by Mozilla (using the Gecko engine).
Songbird 1.2 features an improvement in its library management and also full integration with iTunes. The most noticeable and a welcomed addition is the speed of searching the library.
