Just press space, just like Motherfly said is that if you want to join in you remix this project, not the remixed. Thanks to @Cosmicz__ , he or she told that if you want less lag, you can delete all the songs besides the one your using.
Also I selected a few songs of you. Its in backdrops, then sound. Just don´t try to use the FNAF song, I mean I have Counting Stars in there, & I was about to say BTS in there but I going to in a bit.
