I use itunes/ Music, for my music, import songs, make playlist etc. all fine and well.

But what annoying is often, not so often, I have mp3 files, I download from the web, for examples, songs that accompany a book.
and Just want to hear the mp3 ONce.

And I click on this in the FINDER.

They Open and play in Music, all ok, but then Music seem to create a copy, and this remains in Music, of which I have to delete later.. in in LIbrary

Is this a preference I can undo somehow, super annoying. What other software does something like this?

Now I have a new trick, taking the mp3 and dragging onto Quicktime, but hassle, so be nice to double click these to it's default software Music, but not leave a copy in Music.
