i have unlimited data so i don't mind using my cloud collection but i just have no idea how to add and remove song on my cloud collection for when i listen music on my phone. So if anyone can give me detail steps that will be cool and appreciative.
I'm not aware of any way to remove things from the cloud collection, but here's a guide on using album match to add things. It's somewhat janky, but it does work for the most part.
