Hopefully this is not closed yet and even if it is, I still want to share this idea with @papa-pepper.
I listen to music a lot, in fact so much that I started making my own tracks. After I gained some grasp in doing so, I started feeling how much this activity can empower you and make any day feel more productive and interesting.
So, my proposal is a weekly beat/song making contest where participants have to submit some music that they produced during the week that has to be linked to the genre or theme that was given in announcement post of each week.
There won't be any rules about how the music had to be made. Hell, it can even be recorded live on a phone microphone.
For the people who don't want to buy any specific software to produce, I will recommend the Splice Beatmaker, which is a great easy-to-use online music production tool that can be used free of charge.
