This will be interesting if it happens. The big issue with SoundCloud is that, so long as they have been a gutsy startup acting as a promotional platform for music, rights-holders have stood back and let them exist. I would imagine that an acquisition by a company like Twitter would bring down all sorts of legal complexity - as with YouTube's acquisition by Google. If rights holders pushed for a backdated payment against copyright music on SoundCloud it could be hugely expensive, unless they've quietly managed to put something in place to get around this.
