Nexus 7 tablet; Android 4.4.4

When I run the YouTube app on my tablet, I get this ad covering the top half of the screen and I can find nowhere to tap to make it go away. Is this malware?

Nope, it's not malware....you should be able to swipe the screen or click the OK icon and it will go away...and maybe won't appear next time.

Nope that's a new YouTube add on that enables you to listen solely to the types of music or artists you may listen to.

Thank you all. With your encouragement I dared click on OK. The Music circle disappeared and only the eboutic ad remained, the screen view is back to normal. Initially, I had thought the whole thing was one big ad.
