Also check out the YOUDJ computer version on https://you.dj, it is awesome :

The music is from artists who agreed to be on YOUDJ, please support them!
To thank me for the app, you can leave me a 5* review, it helps me a lot.
To come back to the old YOUDJ app, go to the "Change skin" tab.
We hope you will like the app. Have fun!
