This was detailed in the announcement of the next update. You will be able to use music from a USB stick for editing the clips. I'm not convinced though that you can actually store the music on the PS4 or use the music for anything other than editing clips.. The showed songs could just be part of Sony's music streaming service.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
