iTunes: Smart Playlist for "currently playing"?

[macstatic]

It would be really handy to have a Smart Playlist in iTunes show whatever I'm currently in the midst of listening to/viewing.

A rule for how long something has been played (i.e. everything played at least 30 seconds) would be great for this, but I can't find anything. And the "Plays" only caters for complete plays. Suggestions?

I'm on iTunes 12.8/Mac OSX 10.13 High Sierra.

I don't know if it's possible to make a Smart Playlist for this. It might be helpful for you to know that you can press Command+L to go to the current song playing (in the playlist it is playing in currently).
