How can i delete a song from itunes library and from hard drive?

If I am deleting a song(s) from my iTunes library, I want it to move to the trash automatically.

Using El Capitan, iTunes 12.7.5.9. My library is configured to "keep iTunes Media folder organized" on an external hard drive. It seems to me that songs used to be moved to the trash in previous versions of iTunes, but now they are simply deleted from the iTunes library, but the actual file remains on the hard drive without being trashed, which will result in thousands of orphaned files on my hard drive, and no way to get rid of them or even know they are there.

How can I delete the song and trash it forever?
