"Next, you will be able to choose what plugins you want
to enable by default. Songbird comes with an iTunes plugin, Last.fm
support and song submission, Shoutcast support, and a plugin which
I strongly recommend, mashTape. mashTape is a configurable add-on
which will fetch detailed information about the currently playing
song from various websites. For example, it will show the artist's
biography using the Last.fm wiki, album reviews from Amazon.com,
artist news from Google News, photos, and the most wonderful thing,
it will even embed YouTube videos related to the artist. It's just
great, isn't it? And all these features are possible due to the
fact that Songbird is practically not only an audio player, but a
web browser too. It embeds most of the Firefox browser into it, so
you will be able to search for lyrics or read artist info (other
than that provided by mashTape) directly from it just by opening a
new tab inside Songbird."
