So I signed up for Match a week ago and just realized there is a button that I had to turn on for it to even begin to work on my iPhone 4S. Now that it's on the music section of my iPhone within iTunes doesnt give me the option of what to sync (playlist wise) on my device. I get that I can create a new playlist and add songs to that playlist but what if I just want to have certain playlists on my device? How does that work?
