We strongly advise against using a commercial music recording as the background song of your video, particularly if you’re just looking to enhance the impact of your video. However, if the visual accompaniment to the song somehow “transforms” the original work to create something wholly new and unique, you may have a stronger claim to fair use.
Please also note that purchasing music from digital music platforms does not constitute as a license to use the copyrighted material in your personal works. Copyright owners reserve the right to submit a DMCA takedown request for such uses.
