VIDEO CHARTS SEEM TO HAVE TROUBLE WITH 'Z' TRACK TITLES
I assume there's either slightly different logic for audio versus video because I noticed a couple of songs ("Zombie by The Cranberries" (ARIA DEC 1994) and the more-recent "Zeze by Kodak Black featuring Travis Scott & Offset" (USA NOV 2018)) are not "found" in the appropriate CHARTS - VIDEO page.
However their audio counterparts ARE found and the video files can otherwise be found within ETouch via normal browsing or searching methods.
I think I actually had a similar problem with the audio file for "Zombie" way back in March 2010 under version 5.0.33 (http://www.freeboxjukebox.com/Forum/index.php?topic=2333.msg19036#msg19036 (http://www.freeboxjukebox.com/Forum/index.php?topic=2333.msg19036#msg19036)) (in point 2) and probably better discussed/referenced again in September 2010 (http://www.freeboxjukebox.com/Forum/index.php?topic=2769.msg21075#msg21075 (http://www.freeboxjukebox.com/Forum/index.php?topic=2769.msg21075#msg21075)) where you posit a reason for the problem.
So maybe the current video searching algorithm/indexes is suffering in the same fashion.
