How to disable Apple Music Ads on iTunes?

This has been raised as problem in the past but I am experiencing it now for the first time, despite having had an iTunes account for many years. The issue now is that when I search the Store for a tune and click to play it for a preview, the Apple Music ad appears. I click the 'not now' option and, after several seconds, it goes away but the selected tune does not play and when I click on the tune again...you guessed it...the blasted advert reappears and so ad infinitum! How do get rid of the advert please???
