Hello j00ds,
This is normal when headphones are connected. What may help is to turn off autoplay in the up next queue, which is outlined here: Add music to your queue to play next on your iPhone, iPad, iPod touch, or Android device - Apple Support
"Autoplay takes the work out of choosing what to play next. Just play a song, then Autoplay finds similar songs and plays them afterward.
To see your Autoplay queue:
- Tap the song that's playing at the bottom of your screen.
- In the lower-right corner of your screen, tap Playing Next .
- Scroll down to Autoplay.
To turn Autoplay on or off, tap the Autoplay button in the upper-right corner of your screen. If you turn off Autoplay on one of your devices, then Autoplay is turned off on any device that's signed in with your Apple ID."
Thanks for using Apple Support Communities!
