To upload a video using music from Videostew's background music partner service 'SellBuyMusic' to YouTube, you must add your YouTube channel URL to the workspace you are working in to properly receive the music license.
The newly added Videostew original music tracks can be used without adding a YouTube channel URL. Whether channel addition is required depends on the type of music track you use.
