I actually thought about something like this as both a way to try coding with AI help and to learn some mobile dev. I'm not happy with the default music player on iOS, nor with the one I'm using. I'm only guessing that using ChatGPT and/or CoPilot I could at least get something started pretty quick.

Step 1: A mobile app plays a music file

Step 2: Play, Pause, FF, Rew

Step 3: A list of songs to select from

Step 4: Show album cover

..etc..
