Using music from Soundcloud on Youtube can be risky and could get your channel a copyright claim or worse, a strike.
Only recently a vlogger I watch on a regular basis complained that a musician on Soundcloud who gave permission to use their tracks has now copyright claimed the music in his video and is now running ads on it. This is not the worst case scenario, it could have been worse.
I have created two videos that could help you lower the risk. Hopefully these two videos can help you to avoid problems.
