Q: Can you ONLY delete one downloaded song at a time with Apple Music?  Can you not remove the download of an entire album?

Hello Jonwil78,

If I understand correctly, you want to know if you can delete complete albums that you have saved to your iPhone for offline listening. Yes, the article below will walk you through the process of removing albums from your iPhone or all of your devices.

Delete songs and music videos from your iCloud Music Library - Apple Support

iPhone, iPad, or iPod touch

1. In the Music app, find the name of the song, album, or playlist that you want to remove, and tap the More Options icon .
2. Tap Remove Download to remove the item for offline listening. The item will remain in your library on all of your devices.
   Tap Remove from My Music to delete the item completely, from your library on all of your devices.

Cheers.
