Apple Music

Hello everyone! I have a question. I'm trying to organize all of my music that I've collected over the years and have done this several times with Apple Music already. I have a crap ton of songs that I've purchased and I don't want to buy iCloud storage. I'd reach a limit of how much I can have and it started glitching out and deleting songs, which made me restart the whole process because of my OCD lol! I really like Apple music when it comes to discovering songs, but I'd only like to have Apple music on my phone and not with my PC. So essentially I want to manually sync my purchases onto my iPhone, without it syncing onto the cloud and taking up space. But still keep Apple music on my iPhone so I can hear and discover different songs, and not have it sync to my PC. Apologies if this may be confusing for some lol! Thank you for taking the time to read this and have a great isolation day!
