Hmm, that might be nice if so. I just noticed 100-some songs on my phone now. Also when "streaming" or downloading or whatever it buffers a LOT. Pandora runs great on my drive, as does Spotify, but Match stops the song all the time.
I believe Pandora streams 128k AACs, while your matched iTunes files will be double that. On top of that if not matched an uploaded file could be up to 320k. That's a lot more data to push every second.
That said Match does sometimes stutter more than I'd like, even when playing Matched files from my Mac. My commute is 90% underground and I prefer listening to albums so I download them on my walk to the train. Wish they'd add some manual management/deleting back though. Downloading single tracks wouldn't hurt, either.
