"One more thing...I used to 'deselect all' and then click on the 'date added' to get back to the top of my songs. Now I see there is no select/deselect option in Edit dropdown. There is a 'select all' but deselect was dropped for some reason. Unless I'm missing something I guess that feature was removed? I tried select all hoping then it would provide a deselect all but that didn't work."

It may have been removed.

Looking here, nothing is provided, as far as shortcuts go: Keyboard Shortcuts in Music on Mac - Apple Support
So, remmed this be a feature to Apple. In the meantime, you have to use your trackpad on your MBP.
Recommending this Apple Feedback:
Do Your Part: Report this to Apple. Apple won't get back to you directly, but the more feedback they receive on this, the more they will know what their customers prefer, and what features to include in releases to come. These are just user-to-user forums. Apple barely reads these forums as it is on their own time and will. They will know nothing of your ideas, if you do not provide them with your feedback.
