How to set up a new MBP with Apple Music and iCloud Music Library?

Hi,

I've recently had an accident with my old Mac and had to buy a new one. I'm taking this opportunity to do a clean install to make sure I don't bring any old malfunctions from my old computer.

I had a worry about my iTunes library. I currently use Apple Music and iCloud Music Library. Most of my songs are bought and some come form Apple Music. I'm not sure how I should proceed with my new iTunes library. Normally, I would just need to activate iCloud Music Library on my new Mac and all my music would appear but how will iTunes know what songs were originally mine since they will all be downloaded from the cloud? My worry is what happens when I decide to stop using that service. Apple says it will just remove all Apple Music from my library so will that be all my songs? I'm also wondering about having suddenly all my songs DRM protected...

if that's the case, would manually adding my songs to iTunes and then turning iCloud music library on and merging be a way around it? Would that not create duplicates?

I was wondering if any of you had the same issue and if anyone could help me with this one? And hope I was clear enough. A bit hard to explain.

Thanks for your help/opinion.
