Hi SurferRosa_13,
We appreciate you reaching out to us. We understand that your Music app is playing the same songs even if you have shuffle enabled and you have a lot of songs.
We’d like to gather additional details that may help us be in a better position to assist you.
How do you initiate playing the songs? Are you using a widget, a shortcut, or through Siri?
Also, do you have a different Apple device that is signed in to the same Apple ID?
If yes, are you experiencing a similar issue with your other device? These details can help us in isolating the issue.
In the meantime, we recommend that you check for a software update.
While it isn't inherently assured that an update will resolve the issue, updating to the latest software version for your device can help isolate potential software issues.
Kindly secure a backup and update.
