ALL music stuttering while connected to cellular data (Apple Music/Spotify)

When using Spotify or Apple Music while connected to cellular data, the songs constantly stutter and skip (like CDs used to do back in the day). I have tried EVERYTHING and nothing will fix it. It doesn’t happen while connected to WiFi.

1. It was a problem with my iPhone 12 and it is also doing it with my new iPhone 15 Plus - so it’s not the device.
2. It happens while streaming songs and with downloaded songs on Apple Music & Spotify. I can even turn on “offline” and it still happens, which is bizarre, unless it’s somehow still trying to communicate with a server somewhere?
3. It happens regardless of the audio or playback settings (I’ve tried them all)
4. It happens while connected to T-Mobile, Verizon, and Boost cellular data services - so it’s not carrier related
5. I’ve tried resetting and erasing my iPhone 12 when I had it and I did the same with my iPhone 15 plus and it doesn’t help
6. I did a fresh iOS install with no backup and it doesn’t help
7. It has been a problem with multiple iOS versions, but I’m currently using iOS 17.4
8. I have 64.82GB available on my device, so that’s not the issue
9. All data saver settings are turned off, so that is not the issue
10. I’ve removed unnecessary apps and stopped background processes
11. Restarting the device will help for a few minutes sometimes, but it’s hit & miss
12. The cellular signal is full on LTE/5G/5Guw
13. It happens while listening through the iPhone speakers, Bluetooth connected to a vehicle, and through Apple Airpods
14. It doesn’t matter if Apple Music or Spotify is open or running in the background
15. It is not isolated to a certain city. It happens where I live now, it happened in Iowa and it happened in Arizona. It also happened during both of my moves driving from Iowa to Arizona and Arizona to Kansas.
16. All apps and everything on the device is updated

Doing a Google search reveals numerous other people complaining of similar issues, although explained differently since it’s difficult to explain. Many describe it as glitching, stuttering or skipping like a CD.

There’s clearly some kind of problem and it seems from all of the replies I’ve read, no one seems to know why, nor have a fix, and Apple doesn’t acknowledge anything.

Can someone shed some light on this please before I dump Apple and switch to Android, because it’s maddening being unable to listen to music without it glitching/stuttering/cutting out constantly!

Thanks
