Can't play songs that spotify thinks I own

[NotAnotherLogin]

There are certain songs, for instance Alkaline Trio, which won't play and where Spotify suggests that I sync local the local files.

The problem is I don't own this music!  But just to make sure someone didn't load them on to my computer without my knowledge, I unclicked the seach for local files on both computers I have the client installed. 

Unsucessful.

This, however, worked for when I wanted to play Coheed and Cambria tracks that I DID at one time own, so now I am able to play that.  I assume from this that I was successful at stopping Spotify from looking for local files.  So my problem now is that I am out of computers to unclick "check for local files"

What next?
