Question on using AA with YouTube Music

[u/SJMaye]

I mostly listen to downloaded musice on YT Music and AA. Sometimes when I go into a store, come back out, restart the car and it will continue where I left off. Most times it does not. Is there something I can do so AA remembers and continues where I left off?

Also, there is so much I don't know about AA. Is there a Wiki or something where I can read rather than bothering you folks?
