As your trusted partner, we wanted to take a moment to warn you about some deceptive advertisements we’ve recently seen for illegitimate music promotion services.
Third parties that promise playlist placements or a specific number of streams in exchange for compensation are likely using illegitimate practices without your knowledge. These services can threaten your hard work, resulting in the potential withholding of streams or royalties, or even complete removal of your catalog from streaming services.

Our streaming partners work diligently to ensure streams are legitimate, meaning they reflect genuine user listening intent. If a service finds that you (or a third party hired by you or on your behalf) have boosted play counts through any automated, deceptive, fraudulent or other invalid means (digital bots, “click farms”, payment for placement on playlists, etc.), the service may permanently remove your entire catalog.
If you’re in the market for a music promotion service, make sure to do your research before you hire them.
