For now iTunes and the distribution deals Apple have are a competitive advantage that Apple wouldn't be willing to give up by integrating tightly with Android.

But in a few years time when Google have similar deals in place and any advantage is marginal (if that), it might happen. While Apple aren't really in the business of selling music (obviously they do but it's a relatively small part of their revenue mix next to hardware sales) there is an opportunity there.

That said over time as these deals become more common, the music business is going to be commoditised which will squeeze profit margins. It may be that those lower margins mean that even with access to a significantly larger potential market Apple aren't interested - they've never really been a high volume, low margin business.

I would argue that it has not been done before because Apple needed to give the ipod the competitive advantage. I think that its hard to say what would happen if iTunes now opened up to android devices too. Would the Music Play store sales decrease and Apples music sales increase? Would there be more music Apple sales with both iOS and Android but less iPods sold?

As I said it is hard to say what would happen and by how much.
