iTunes Match Download on iPhone

[impaler]

I have 18K+ tracks in iTunes Match, and all is well at home and on my Apple TV, for streaming the music. When I enable iTunes Match on my iPhone 4S, it seems to pull a bunch of data, as the activity meter is spinning around in the Music app. I didn't enable iTunes Match to show the entire library of 18,000 songs, just turned it on. What is it downloading or syncing just by turning it on?

That's over 60 GB of data? Hope it's not downloading it.

If it's trying to download my entire iTunes Match library (which it's shown it doesn't work that way), that's more like 130GB (I upgraded everything it matched to 256kbps AAC files). Maybe it's syncing playlists?

I think it's only downloading the list of songs in your iCloud, artwork as well.
