unable to delete song from libray that I never saved in the first place

A song appeared in my Library that I never played or saved to my Library. The drop-down menu does not show a "Delete from Library" link... but it does however show a "Download" link. How do I get rid of this track in my Library???? I tried restarting the app along with a number of things. I never purchased the track and in any case have all iTunes music set to "hidden".
