Actually, I use Audacious for DJ work. I’ve tried “real” DJ software and much of features are pointless unless you play at raves. I volunteer at a nursing home (where there are 30 year olds, up to my age group of 60). Audacious allows quick access to my 19,000 + music collection. It allows me to use my laptop’s main screen to run the player and queue songs while I use the CRT port display the album cover and the visualization animation as a second display device for the residents to see on a 70-inch flat screen TV facing them. The tunes cross mix properly and seamlessly between songs.

Clementine does a nice job too but takes more CPU horsepower to run and still doesn’t offer the features Audacious does for my DJ volunteer work.
