Summary: Nightingale is a cross-platform and extensible media player. It's derived
from the Songbird media player (to continue Linux support) with its GUI
based on Mozilla XULRunner and GStreamer used for audio playback.
Songbird addons can still be used, it supports MP3, AAC, Ogg Vorbis, FLAC,
WMA files, and MS or Apple DRM-covered files. It adds MP3/RSS playlists,
custom mixes, scanning local media directories, a minimized user interface,
Last.fm integration, meta data editing, iTunes import, custom themes.
