What happens to Mix Radio after 3 months on Lumia 730?

[Windows Central Question]

We can download unlimited songs for the first 3 months, right? After that, we can still stream unlimited songs. This is just my first month. I have downloaded a few songs. They appear not only on Mix Radio, but, I can also see them in "Music". So, my question is, after 3 months, can I still listen to these downloaded songs through "Music" after 3 months for free rather than streaming on Mix Radio???
