Amarok is a free software music player for Linux. Amarok serves many functions in addition to the basic function of playing music files. For example, Amarok can be used to organize a library of music into folders according to genre, artist, and album, can edit tags attached to most music formats, associate album art, attach lyrics, and automatically "score" music by keeping play count statistics.

Although a more technical list of features is listed below, here are the primary functions or uses for Amarok:

* Playing media files in various formats including but not limited to (depending on the setup) FLAC, Ogg, MP3, AAC, WAV, Windows Media Audio, Apple Lossless, WavPack, TTA and Musepack. Amarok does not play digital music files embedded with DRM.
* Tagging digital music files (currently FLAC, Ogg, WMA, AAC, MP3, and RealMedia).
* Associating cover art with a particular album, and retrieving the cover art from Amazon
* Creating and editing playlists, including smart and dynamic playlists. The dynamic playlists can use such information as the "score" given to a song by an Amarok script, and the playcount which is stored with the song.
* Synchronizing, retrieving, playing, or uploading music to the following digital music players: iPod, iriver iFP, Creative NOMAD, Creative ZEN, MTP, Rio Karma and USB devices with VFAT (generic MP3 players) support.
* Displaying artist information from Wikipedia and retrieving song lyrics.
* Last.fm support, including submitting played tracks (including those played on some digital music players) to Last.fm, retrieving similar artists and playing Last.fm streams.
* Podcast

From version 1.4.4, Amarok introduced the integration of Magnatune, a non-DRM digital music store, enabling users to purchase music in Ogg, FLAC, WAV and MP3 formats.

Some of these features depend on other programs or libraries that must be installed on the computer to operate.
