let's get this out of the way up front -- I'm old....not 'tech ignorant' but no Steve Jobs either. My question: is there a music streaming service that provides the ability to keep downloaded tracks even after I've cancelled my subscription? I'm Amazon Prime now, which wife and I use regularly, but I understand that should we drop that at some point, I'll have no access to the hundreds of songs I've downloaded over the years. How can I avoid that? Also looking at adding Music Unlimited as there are many tracks not available on regular Prime Music.
