We strongly advise against using a commercial music recording as the background song of your video or live event, 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 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.
If you are looking to license music for your video, consider one of the following websites:
Also, if you use Vimeo's creation and editing tool to make your video, you can choose from a library of commercially licensed music.
