Amazon currently has a promotion with Disney+, if you have never had Amazon Music before, going to this link you can get a free six months of Disney+ when you get Amazon Music.
Ofcourse why pay for the Amazon Music either.
If you have a burner Amazon account, go through the normal process, and the payment will be through Disney+, just use a VCC with a $1 limit or an empty Paypal. It lasted me about a week or two if I remember correctly before it is disabled, but then just do the same process with a new Amazon & Disney account if you do not wish to wait a few more weeks because your subscription will be on hold before being canceled. So just two Disney+ accounts should work fine.
