Have a Quick Look
I was going to write this up for downloading but it's almost too simple.
Select a track in the Music app and run this script to open a Quick Look panel displaying the track's file, ready to play.
tell application "Music"
try
set sel to selection
if sel is {} then return
set theTrack to item 1 of sel
tell me to doQuickLook(POSIX path of ((get theTrack's location) as text))
on error
return
end try
end tell
on doQuickLook(loc)
try
do shell script "qlmanage -p " & quoted form of loc & " >& /dev/null &"
end try
end doQuickLook
