Original: Amarok is a free software music player for Linux and other varieties of Unix, as well as Windows since version 2.0 (through KDE for Windows). It makes use of the KDE Platform, but is released independently of the central KDE Software Compilation release cycle.
Simplified: Unlike most KDE programs, it has its own schedule for releasing versions, so a new version of Amarok might not be released when a new version of KDE comes out.
