How to Delete Active Playlist

I would like to delete my Active Playlist and start from scratch. But I cannot seem to find anyway to do so. I like to be able to put that playlist on and just listen while I do mindless tasks (walking, doing dishes, etc). But, I really don’t need or want to hear old beginner material from 2 years ago that is way below my current level.

I can delete manually made playlists. But it appears that I have to delete things in the Active Playlist manually, one by one. This is going to take hours! Surely there is an easier way to do so.

Please help!
