I use the above app to collate plays etc because I find it far more accurate than LastFm although I do use that one as well. I tend to get several duplicate plays with LastFm. Soundwave works with Itunes, Apple players both Ipad and Iphone, Spotify, Rdio, Google Play Music All Access, Youtube and Deezer. It also works on the Android in built players. I don't pay any attention to the playcount's or last played within Itunes due to Itunes Match totally destroying all that information. I am not sure if it is possible but I thought I would mention it.
