Explicit content songs

Hi RottingApple1,

Thanks for posting in Apple Support Communities. First, make sure that you do not have any restrictions that might be causing these songs not to play correctly. The guidance from Use parental controls on your child's iPhone, iPad, and iPod touch can help you check for content restrictions.

"Set Content & Privacy Restrictions

1. Go to Settings and tap Screen Time.
2. Tap Turn on Screen Time, then tap it again. Choose "This is My [Device]" or "This is My Child's [Device]."

• If you're the parent or guardian of your device and want to prevent another family member from changing your settings, tap Use Screen Time Passcode to create a passcode, then re-enter the passcode to confirm. After you confirm your passcode you'll be asked to enter your Apple ID and password. This can be used to reset your Screen Time passcode if you forget it. 
• If you're setting up Screen Time on your child's device, follow the prompts until you get to Screen Time Passcode and enter a passcode. Re-enter the passcode to confirm. After you confirm your passcode you'll be asked to enter your Apple ID and password. This can be used to reset your Screen Time passcode if you forget it. 

3. Tap Content & Privacy Restrictions. If asked, enter your passcode, then turn on Content & Privacy Restrictions."

Also, this is unlikely to be related to Dolby Atmos but if you do use the feature, test to see if the same occurs when disabled. That might isolate this a bit. As mentioned in Listen to Dolby Atmos music on iPhone, you can do that from Settings > Music > Dolby Atmos.

All the best.
