Qmmp is a Qt-based music player with a Winamp-like interface.
The program opens with a compact, minimal look: a simple player, playlist manager and equalizer. Drag and drop a few files and you can play them with a click.
If you don't like the interface, it's easily changed. The program comes with several skins (Settings > Appearance), as well as supporting skins for XMMS and Winamp 2.x.
Whatever Qmmp looks like, most functions are easily controlled by hotkeys. These are also fully configurable, so feel free to tweak them until you're happy.
Explore the menus, right-click things and you'll discover other features, including DSP effects, cover art and lyric support, tag viewing and editing, stream browsing, audio format conversion, ReplayGain support and more.
Version 1.3.4 changes include:
added qmmp 0.12/1.3 config compatibility;
disabling global shortcuts during configuration;
fixed memory leaks;
fixed issue caused by sending same metadata several times in a row.
Qmmp is a compact and configurable media player. Winamp fans will probably love it, but if you're looking for something simple and straightforward, you might not be so convinced.
