I ftp'd the album.dat file in question to my desktop, where I could edit it. I could not change permissions on that file type on the server so I renamed the file to albumBAK.dat and ftp'd the changed file back up to the server.
The change you want to make is to take the permission catagory in question and change it to:
Text Formatted Code
...s:13:"canChangeText";a:0{}...
Where the "0" in:
a:0{} lists the number of list items that follow in the "{}". The default is NOBODY, so you don't want anything in that list (therefore "0{}").
Now don't assign a group permissions to an album unless you mean it.
