iTunes Match in iOS 6 does NOT stream

In June, many reported that in iOS 6, iTunes Match streams, and will download if you press the cloud button. Well, it's not the way the app works. I checked my "about" setting on my iPhone 4and had zero songs, and 3.7 GB of free space. I turned on iTunes match. It took a bit of time to recognize my 20,000 songs. I then played a bunch of songs (and not all of the album art showed). When I finished, I went back to "about" and it had 15 songs and my free space was down to 3.5 GB. I then turned off iTunes match, and, after a few minutes, went back to "about" and the songs were gone (back to zero) and my free space was back to 3.7 GB. It is not a true streaming service. ****, Amazon's Cloud player for iOS works great, and the album art shows up immediately (unlike what I just experienced with iTunes Match -- perhaps it had to do with so many songs in iTunes). Very disappointing, Apple. The Apple TV streams (it used to have a hard drive in it but it was changed to a streaming service), why not make iTunes match the same.

I use an app called Orb, which allows me to stream from my MacPro over wifi and 3G. It's a bit slow to start, because it has to go from my iOS device, to the Orb service, to my MacPro and back. But it works. If Apple doesn't change iTunes Match to a true streaming service, then I will drop it. No use to me.

Anyone have a similar experience?
