How to get an applescript to play a song file

applescriptquicktime

Okay so I want an applescript app that plays a song. The song isn't already on the computer and it's contained inside contents/resources of the app's package contents. This is my current code

tell application "Finder"
    set apppath to POSIX path of (application file id "com.apple.ScriptEditor.id.play" as text)
end tell
set song to {apppath, "/Contents/Resources/song.mp3"} as string
set songpath to POSIX file song as text
tell application "QuickTime Player"
    activate
    open songpath
    play the front document
    tell application "System Events"
        set visible of application process "QuickTime Player" to false
    end tell
end tell

On my computer this code seems to work. However when distributing it, other computers get an error in quicktime. The document “song.mp3” could not be opened. The file doesn’t exist. Any help?

Edit: Fixed an incorrect variable which doesn't fix the problem because I changed the code to post it here and mixed it up.

Activating QuickTime is a lot of overhead for playing a single file.

You can use afplay instead:

do shell script "afplay " & songpath

The code below it what I'd use to replace the original code offered as there appears to be a bug in AppleScript when using the do shell script command in the manner originally presented that isn't present went the code, in a representative manner, is run in a bash script in Terminal.

Note that anytimeopen for access is used, it needs to be coded to trap any errors and try and close the file, which this attempts to do. That said it is not necessarily then only error handling I'd employ and all coding answer I present are done so as proof of concept and the onus to write code employing reasonable error handing is yours to fulfill.

As coded, this will create the target file if it doesn't exist while adding the text to add to it and if it does exist, places the text to add as the top line of the target file.

set targetFilePathname to (POSIX path of (path to desktop as string) & "My Fruit Log.txt")

--    # set theTextToWrite to "This text will be written at the top of the file." & "\n"    
set theTextToWrite to "This text will be written at the top of the file." & "\n"
set theOriginalText to ""
try
    set theOriginalText to (read targetFilePathname) as string
end try
--    # set theTextToWrite to theTextToWrite & "\n" & theOriginalText
set theTextToWrite to theTextToWrite & "\n" & theOriginalText
try
    set referenceNumber to open for access targetFilePathname with write permission
    write theTextToWrite to referenceNumber starting at 0
    close access referenceNumber
on error eStr number eNum
    display dialog eStr & " number " & eNum buttons {"OK"} default button 1 with title "File I/O Error..." with icon caution
    try
        close access referenceNumber
    end try
    return
end try
