Apple do not license their DRM to third parties. The only way to play music bought off the iTMS is with iTunes or an iPod.

TMS AAC files will never work with Scratch LIVE or any other program that is not iTunes, unless Apple licenses its DRM (Digital Right Management) technology. Currently Apple has a proprietary system for protecting copyright material and all music downloaded from their store can only be played on iTunes or an iPod.

HOWEVER, the files you download from iTunes Music Store are NOT just plain AAC files. They are AAC with the FairPlay DRM embedded. This is the problem. To use a FairPlay DRM AAC file you must have the decode stuff licensed from Apple - it's impossible to play otherwise. And Apple (in their infinite wisdom) have so far refused to license FairPlay to anyone else.

So the upshot is this - if you create the AAC file yourself (in iTunes, or any other app) then you will be able to play it on winamp, or FS2, or anything else which supports AAC. However, if you buy a track from iTMS, you can ONLY play it in iTunes or on an iPod. Not on FS2, not on your Rio mp3 player, not in winamp.

I dont understand why Rane wont update scratch live to read Itunes files. I've downloaded a lot of music off Itunes music store and i cant play any of those files because serato cant read the format.
I was wondering if or when this will be resolved.

Thank you
