I use MPATool.

What I am wondering though is whether there's a way to add artist background without using MPATool so that, say, for example, I can copy over the songs to another WP device and not need to run MPATool because the artist backgrounds have been embedded directly to the songs.

You could try the method in here: HOW TO INSERT BACKGROUND IMAGES IN MUSIC FILES.

Thanks for the reply.

That's not what I need though. That's for album art, which is different from the artist background used by Music+Videos
