G'day from Oz.
I've already posted something like this somewhere else, but here goes.
Your QuickTime preferences are probably set to something like 'Use QuickTime to play internet music.'
You can re-set your files to iTunes using something like File Buddy.
The file type should show as .mp3, and set the file creator to 'hook'. Once you've done this, it will be added to FileBuddys pop-up choices.
The file should then play via iTunes, and be added to it's library. You can move it anywhere. Bit cumbersome though.
To automatically re-set downloads to iTunes, try setting the iTunes prefs to 'play internet tunes' and 'play automatically' (or something like that).
The other way is to drop them on an Applescript droplet which will convert and play them, automatically adding them to the Library.
I can modify one of my own scripts for you if you like.
