Quick note about expecting free music for your videos…if you create for free and don’t monetize your channel or the videos, maybe that’s one thing. But really, if you like a piece of music and want it for your video, you should pay the creator. Even if it’s as low as $25-$50 for non-exclusive use, that’s showing your fellow artist/creator a modicum of respect. Especially if you monetize the channel or commercialize the videos. Pay the people who help you create.
