To clarify :

The reason the composer and publisher are almost 100% likely to say no in your case has to do with the fact that you'd essentially be able to make money off of the work someone else has done. Even if you don't produce CD's and go straight for a digital release such as spotify, iTunes, etc, you'd eventually be able to derive a fair amount of money from the sales/streaming of someone else's work. In the case of recordings that you had produced, you would of course be entitled to earnings, and the composer would get something out of it too in the form of a royalty ; in your particular case, I doubt that the composer/publisher would find it to be fair to have their original recording giving a payout to someone else, as that is ultimately what would happen given the way most digital platforms are structured right now.

Not trying to put a damper on your efforts, but that is most likely how they will see things.
