I recently noticed that my iPhone 4S with iTunes Match enabled is no longer updating play count and last played when syncing with iTunes. The iPhone is not my primary iPod, but I do use it on occasion and I do have a Smart Playlist that uses play count as criteria.
There are several ways that you can browse your music library in iTunes. Its grid and Cover Flow views are really great for picking out an album by its artwork, and you can play an individual track within seconds of it springing to mind, just by typing in the search bar. But sometimes you’ll want to kick back with a tailored selection of songs, or create a playlist for a party.
My wife and I share the same iTunes music library and while most of our music taste overlap, there is the wayward song or artist that she listens too that I can't stand.
Of course, I only notice that an artists or song has snuck onto my iPhone while I'm listening to my iPhone. I used to think that I could remember to remove the offending song from my iPhone the next time I synced the device,. But of course, I always forgot. I figured out a quick way to remove the offending song while on the go.
