"One of my favorite open source applications is Amarok, a music player with an intuitive interface that makes boring tasks such as organizing large music collections less troublesome. The only problem with Amarok is that it's a KDE application and I'm a GNOME user. Although there's nothing wrong with running KDE programs on GNOME, they take a long time to start, since they need to load the KDE libraries and components they depend on first. I've found a good alternative in Exaile, my new favorite media player for Linux.
"Exaile is similar to Amarok, but it's based on GTK+ (the GIMP Toolkit), the same GUI toolkit GNOME uses, and thus it loads almost instantly on GNOME and integrates nicely with it..."
