Hi hamedredrose,
it seems that you took an older code-version as your source for the needed changes.
There is a bug again in your versions with double quotation marks, that was corrected by dano in 2013.
[WS] iTunes
If an artist, an album or a track-title has double-quotation marks in it, all content after this quotation mark is cut off.
Look for yourself and for example search for:
Artist: Bonnie "Prince" Billy
Album: The Letting Go
where as artist only Bonnie is shown.
or
Artist: Duke Ellington
Album: Jazz Moods: Hot
where track 13 should show Take the "A-Train" and instead only shows Take The
At the moment I am looking over my previous working script without that bug but I am not able to find the responsive code difference.
