Mixxx is software for DJs that provides everything needed to create live mixes. It allows you to beatmatch songs and crossfade them together, like you would with turntables and a mixer. It runs without any extra hardware, and offers a wide range of advanced features including comprehensive MIDI controller and vinyl control support. To obtain the lowest latency and highest responsiveness, it uses hardware video acceleration and takes advantage of multi-core CPUs.

BlindTux is a musical quiz game. The goal is to identify the artist, title, or year of a song by choosing an answer from among 4. The maximum number of players is 4. For now, it is played with the keyboard, but soon players will be able to choose with controls they want: keyboard, gamepad, or maybe buzzer.
Muxic is a minimal user interface to XMMS2. It is inspired by Winamp Classic's windowshade. It is only meant for controlling and monitoring playback, not for managing a media library or even a playlist. To actually play music, it relies on the XMMS2 (the X-platform Music Multiplexing System 2) daemon, and another XMMS2 client must be used to put some music in your playlist. Muxic's keybindings are based on a subset of Winamp Classic's keyboard shortcuts. Muxic announces track changes using Growl.
