Music indirectly played a role in many episodes; Elliott Markham for instance also got convicted based somewhat on music.
(And of course the 10-minute stifling rendition of "Volare" during the murder on Troubled Waters).
I still don't think that Poupee Bocar / Rosanna Wells is a terrible singer. Even if I did, her wardrobe in that particular scene would make it all right.
Grant, I was not saying that she is a bad singer; just the length of the song during the murder was too long.
Yes, I often feel the same way about VERY drawn-out songs, even some "iconic" Ones.
