Music search and Album artwork download?

Does Apple Music have a search feature for purchasing older classic albums? I'm not finding a button for that.

Do you still have album artwork available for download? There is a button for artwork but it never works

I'm not above having just a digital copy but it needs to be on my hard drive.

I used to use these features with iTunes. Lately I'm not finding that these features work.

Now that I'm retired, I would like to flesh out my collection of owned music. I'm not interested in a subscription service. There are lots of ways to add to my collection but iTunes was a convenient source.

I use Apple Music on my Mac mini, it works just like iTunes did and I like it. I have a different music player on my Android phone and I like it also. If Apple thinks it needs to squeeze another subscription out of me, I will migrate to another platform. I have thousands of songs on my Samsung phone and I like the convenience of playing a playlist over any bluetooth receiver I'm near.

Any help with this would be appreciated.
