Can't change mp3 file association

Question

I am trying to make mp3s open up in quicktime instead of iTunes. I tried changing the association by 'get info' and changing all to quicktime however this does not change the association.
I have also tried the following in terminal:
System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchSer vices.framework/Versions/A/Support/lsregister \ -kill -r -domain local -domain system -domain user
This didn't help either.
Please help!

Answer 1

As I mentioned, just because files have an mp3 extension does not mean that they are all of the same type, so I did a search to see if there were any rogues hiding somewhere.
I didn't see anything, so I changed the associations of types MPG3 to QuickTime, and they all changed as expected. You might try changing the associations from a new user account, or check the types of the files you are trying to change to see if they match (my .mp3 files have a file type of MPG3 and a content type of public.mp3). If you don't have a utility handy, the following AppleScript will put up an information alert for each selected FInder item:
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFEE80;
overflow: auto;"
title="this text can be pasted into the Script Editor">
-- get file types of current Finder selection
set HomeFolder to (POSIX path of (get path to home folder))
tell application "Finder" to get the selection as alias list
repeat with AnItem in the result
set ItemPath to POSIX path of AnItem
if ItemPath contains HomeFolder then -- shorten the item name a bit
set TheItem to "~" & text (count HomeFolder) thru -1 of ItemPath
else
set TheItem to ItemPath
end if
set {kind:TheKind, file type:FileType} to (info for AnItem)
set TheKind to "Kind = " & quoted form of TheKind
set FileType to "File Type = " & quoted form of FileType
set ContentType to (do shell script "mdls -name kMDItemContentType " & quoted form of ItemPath)
display alert ¬
"File Types" message ¬
TheItem & return & return & ¬
TheKind & return & ¬
FileType & return & ¬
ContentType ¬
buttons {"Cancel", "OK"} cancel button "Cancel"
end repeat
</pre>
