VirtualDJ Free Home Edition is used by DJs to replace their turntables and CD players and use digital music instead of vinyl and CDs.
It will let you organize your collection of tracks, group them easily in a DJ-friendly way, use filters to find the hot songs, find compatible bpm or key, access your previous playlists, etc. And if you're missing a track, it will automatically find it on the Internet and stream it directly (*requires an additional subscription). And, using the millions of automatic reports we get every day from other users around the world will give you meaningful advice on which songs other DJs consider to go well after what you just played.
VirtualDJ Free Home Edition can play audio tracks and video or karaoke if you connect your computer to a projector or the club's screens.
