itunes 12.6 does not allow drag & drop to create a play list. What to do instead?

I don't know what really is wrong with the team that manages itunes in apple. Because seriously every time they release a new update, they destroy something that had worked well for years. Now I updated itunes to 12.6.2.20 which is the latest as of now, but I no longer am able to create a simple playlist like I did before. I used to drag a folder of my desired songs and drop them in the section that says edit playlist but now once I do that, the mouse cursor changes to a stop sign and after releasing the left click, nothing happens. Can any body tell me what can I do to create a simple playlist without adding all songs to the itunes library and choose from them? As far as I know, that is the only option left which means that I have to add 3000 songs all at once to the library and choose from them for each of my playlists. Oh and by the way I am on a Windows PC. Thanks.
