They went to YouTube music, right? I actually have over 1200 songs saved to my phone and used to use the Samsung Music app. When I was forced to upgrade my Galaxy S20 to the Galaxy S21 (dropped it and broke the screen), the Samsung app only allowed for specific music formats. Notably missing was WMA. I found that comical, as Samsung and Microsoft are partnered on having Samsung phones sync with Windows 10 through the "Your Phone" app. Yet, they won't accept Microsoft's audio format; while accepting M4A (Apple's audio format).
Did you use Google Music to stream or to listen to music saved to your device?
