I totally love iTunes for its user interface and have been using it since day 1, but recently I have been enjoying Play more often. First I was using it only to play FLAC audio and preview downloaded audio but suddenly I realized that everything sounded better through Play, I mean the soundstage opened and somehow the music gained a more 3D image. For sure it has something to do with it's 32 bit floating point playback, I don't know but some how it sounds really good. The interface of Play is nothing special, I would say it is very basic, but usable.
Give it a try and judge for yourself.
