There's an application that I wanted to download but it is only available in US region. My apple account is in MY region and I have apple music subscribed, therefore they do not allow me to change my region until my subscription is over. Will all my subscribed playlist be gone if my subscription end and I change the region to US before I switching back to Malaysia and resubscribe apple music?
Register US region account -> Switch App Store to US, download any free app and you can register for US account (use US address generator to fill in details)
Your MY Apple Music subscription will still be there, just that when you switch App Store region,
all downloaded music will be gone, but your playlist and everthing in iCloud Music Library will still be in the cloud. You will need to redownloaded the music when you switch back to MY App Store.
Alternative way is to use iTunes on Windows/PC, download the app, and transfer to your phone.
Hope you find this information useful.
