iPad software update via Mac

Are you referring to using a computer to update your iPad? If so, neither Music nor iTunes is used to update iPad on Mac now. Instead, it's done through the Finder - Update your iPhone, iPad, or iPod touch with the Finder - Apple Support

If you have an older Mac (with macOS Mojave or earlier), you will use iTunes. See here - Update your iPhone, iPad, or iPod touch with iTunes - Apple Support

If not, please describe your question in greater detail - Writing an effective Apple Support Commun… - Apple Community

Can you better describe your question? The only reference to the Music app in this link is about removing music in the Music app to free up space. It's not about the Music App vs iTunes in any way.
