A competitive DJ game, where you mix popular songs. The tools let you layer the tracks over one another, just as a real DJ would do. The audience reacts to your selections. You can share your mixes with the Fuser online community. You can play by yourself to go for a high rating, or you can invite a friend who also owns the game, to go head to head in a DJ battle. Here's the IGN demo that nicely illustrates the gameplay https://youtu.be/Ojnt7Pe7C3c

Note that the base pack comes with 25 songs. The VIP package costs a lot more, and give you access to hundreds of popular songs.
