This isn't exactly what you are asking about, but you might prefer this. The iPhone can control iTunes on your home computer wirelessly. So, if your computer is now hooked up to your receiver, all you need is to download the free iPhone app Remote. Then, your phone displays all the music in your computer's itunes and lets you play them out your computer, to your receiver. That usually gives you a larger library of music than would fit in your iPhone, plus your phone is not shackled to your receiver - its in your hand in your easy chair. You can control the playback volume and everything.
