Slightly different model. But iTunes match seems pretty interesting. I think iTunes needs to open up their catalog to streaming ... that would be too convenient to pass up. I love the social/discovery aspects of Rdio/Spotify/Mog. I don't like having to go find an album to download and see if I like it or find a myspace stream or something ... it's awesome to have it all in one location.
This is true. Actually, the ability to stream anything is what will keep Spotify and Rdio prevalent over iCloud. I'm on the verge of jumping to the $10/month Spotify.
