I joined Epidemic Sound to get music for my YouTube channel; They gave me a free subscription month. I downloaded music and used it for my YouTube videos! Then, after the month decided that the YouTube Audio Library itself is better, bigger, free and easier, I stopped the subscription.
Now Epidemic Sound has claimed copyright in all my YT videos with their music, the music that I downloaded while the subscription was active!
So be careful! Unless you get a lifetime subscription, your YouTube videos …
DO NOT USE EPIDEMIC SOUND royalty free music! Here is what happened to me!
