Apple music on iMac stops playing after each song

I have Catalina 10.15.7 installed on my iMac. All my music consists of legally purchased CDs that I imported into iTunes. Playback always worked fine, but since I upgraded to Catalina I noticed the following. Although I had not changed any settings, songs on any album were shuffled. I did notice that under Controls>Shuffle "on" was selected. I deselected that option, but ever since, Music stops playing after each individual song. I tried all the options under that Controls>Shuffle (on,/of), (songs/albums/groupings), but nothing would bring continuous play back. Also not after I restarted my iMac.
