Your 2 screen shots doesn't really line up.
Your external drive is apparently mounted on JukeBox11 not JukeBox1
Do a
ls -l /media/musicpi/JukeBox11
and
sudo ls -l /media/musicpi/JukeBox1
and
sudo blkid
Something distinctly weird is indeed going on....I have no idea where the JukeBox11 came from...least, I don't remember!!
