delete music from iPhone and stop it from loading on phone

Good day to you wednesdaytgw, 

It sounds like you’re encountering an automatic sync happening when you connect your iPhone to your computer. 

From the Summary pane look under Options and make sure that ‘Automatically sync when this iPhone is connected’ is unchecked. Then click Sync or Apply at the bottom right. 

To make changes to what data is currently synced, go to that tab from the side bar and remove the checkmark. For example, if you click on Music you’d remove the checkmark next to ‘Sync Music’, then click Sync or Apply at the bottom right to have the sync happen. 

The following article has some additional details and screenshots - Use iTunes to sync your iPhone, iPad, or iPod with your computer

You may also be seeing music that is available to be downloaded, music that was purchased from the iTunes Store and not music that is currently downloaded to or stored on your iPhone. You can disable that on your iPhone by going to Settings > Music and turning off 'Show All Purchases'.

Thanks. 

wednesdaytgw,

To clarify, when you deleted albums from your iPhone, did you notice they were in fact deleted from anywhere else? While the warning is always great to receive, if it’s not actually removing anything then the message may be nothing to be concerned about. 

Let’s check another thing. In Settings > General > iPhone Storage > Music it’s going to show you all the downloaded music. Do you see all that music appearing here? We want to be sure that the music isn’t showing as available to be downloaded, but isn't actually downloaded. 

Thank you for checking. 

wednesdaytgw,

If you’re using iCloud to sync data, or using Apple Music or iTunes Match, then deleting it from one device will delete it from all devices that are signed in with the same Apple ID and have iCloud or Sync Library enabled. On your iPhone if you go to Settings > Sync Library do you see that setting and if so, is it turned on? 

Thanks. 

wednesdaytgw,

The majority of the music you’re seeing is available in your library and to be downloaded or streamed, though not currently downloaded. You can go to Settings > Music and turn off ‘'Show All Purchases’, if you prefer not to see it. 

You had expressed a concern on turning that off and not seeing some purchased Tones. You can view those in Settings > Sounds > Ringtone. You’ll see downloaded tones appear at the top of the list along with an option to visit the Tones store or download all your purchased tones. 

Additionally, you can reach out to Apple Support for assistance, as we want to make sure all your questions are answered. Here’s their link - Contact Apple Support.

Thank you.
