Clean versions of explicit songs are available on Soundtrack. However, they are also marked as explicit and you need to disable the Explicit filter to play them.
Here's why… It's been proven that listeners often "fill in the blanks" when listening to the clean version of a song. They can interpret the song as explicit, even though they actually hear a clean version. We don't want any unhappy customers, so we mark these tracks as explicit.
If you believe a song has been incorrectly marked as explicit, contact support@soundtrack.io and we’ll review it as soon as possible.
