One Album will not Play

[Tim Curtis]

I ran a quick test and added "Prince" to the artist tag of a track in my Test_mixed collection and there were no issues in the Library.

         

I'm still leaning toward a corrupt tag that caused you issue. Maybe the process of editing it removed the corruption. If you still have the original track feel free to zip it up and PM me a download link. I'll see if I can repro.
