You'd only really need the acapella of the song and a program like GarageBand or a couple of tune samples and Audacity.
Whatever the case, it's a lot of work.
Garageband and Audacity? Nope. Audition, or ProTools, or Logic. And the only good fan remix of le Disko is the La Dolce Vita remix of Le Disko. It's on their myspace, and the creator is a frequent poster at the first shiny toy guns forum.
And you're not getting any Acapellas from them. They can't even legally release it. It's up to the record label.
And all those rare songs- I released them as a torrent on The Pirate Bay. Most of them, anyway. And the Le Disko files I'm not gonna be the one to leak- it's too much to upload, and I don't think most people could do much with them (the demographic of people who could use it is the same as the people who buy or know where to get these things). Torrents are your friends people. (EDIT: I realize this sounds harsh. I'm just saying, STG might get pissed about that leak),
Sorry, but can't give it out.
