Multiple Apple Music subscriptions on one Apple ID?

Hey--

I've had an individual Apple Music subscription for years, but I recently learned that my Verizon plan allows for 6 months of Apple Music free. I applied that to my apple ID and was prompted to cancel one of my Apple Music subscriptions the next time I opened the Music app. I canceled my original subscription to benefit from the 6 months free, and my original subscription will end at the end of this billing cycle in about a week.

I'm just hoping to ensure that my new subscription via Verizon will keep all of the songs I have under my old subscription. I'm thinking it would, as it's the same Apple ID. But I really don't want to lose all of my music, so I'm hoping someone can quell my fears.

Worst case scenario, I'm guessing I could renew my old subscription and my music would return, yes?

Thanks for any assistance!
