Probably nothing new to a lot of you guys, but to the ones that haven't thought of this yet, this is an awesome service for "crate digging." Set up a couple playlists... then launch a radio station for whatever genre you want to listen to. You can skip through songs that you want to hear more of and then drop them into playlists for later purchasing. I give the songs in my playlists a thorough listen through before purchasing. Currently you have to purchase through you favorite service (Beatport, iTunes, etc.,) in the U.S. but I think the UK and Europe can purchase inside the Spotify application.
