I am signed up with the same ID as the original phone. When I backed it up I used the iCloud backup and now everything is stored in iCloud, but I want to discontinue using iCloud and just have everything physically on my phone. I only have one apple device, being this phone, so I don't need the "share between your devices" feature which is really the only reason to have iCloud.
OK, need to make sure you understand that iCloud and iCloud Music Library are entirely different things. You have a backup in iCloud, but that backup is only for certain things, and is a snapshot of your data and media at the point in time when you backed it up. If you do not continue to back up to iCloud, then if your phone is lost, stolen, or damaged beyond repair, then you will not have a current backup to restore from. Also, iCloud syncs specific things like Contacts, Calendars, Notes, Photo Stream, Reminders, etc.
So, sharing with other devices is not the only reason to have iCloud.
Do you have iTunes on a computer that you sync and back up to? You need to have some repository of your phone's info. Storing valuable memories and info on a device is a disaster waiting to happen. Photos need to be imported to a computer or uploaded to a cloud archival service like Dropbox or Flickr. Contacts need to be stored either in iTunes or in iCloud.
iCloud Music Library is a specific cloud service that is used for Apple Music and iTunes Match. The info I provided in the previous response tells you what you can do with Apple Music without having iCloud Music Library turned on. iCloud Music Library does not use any of your iCloud Memory.
Understanding the conceptual foundations of these services is critical to making decisions that will result in the environment that you want on your Apple account. If you have a clear understanding of how they work and what they can and cannot provide, you avert the kinds of situations that people post here all the time about. Your phone is not a safe place to keep anything of value because it is subject to loss, theft, or accidental destruction.
P.S. Link for Apple Music vs. iTunes Match which explains how they work in a complementary manner: APPLE MUSIC VS. ITUNES MATCH
Best of luck,
