UnrarX is not making a folder for expanded contents.

I am using UnrarX to open a music album saved as .rar
What I would expect is that the program would create a folder by the same name, and put the expaned contents in it. However it does not do this. It simply expands the contents all over the folder in which the .rar folder was! So I have a big mess. How do I make it do what I would expect? (I'm sure that's how it always worked on Ubuntu and Windows whenever I expended a compressed folder).
Thanks!
