I tried it and it's just okay. Nothing major. I turned off the "you should buy" part, and just use it to create playlists. I'm not sure exactly how it creates a playlist though. For example, based on "Super Trouper" from the MAMMA MIA soundtrack, it created a playlist that included "Happiness" from PASSION, Kristin Chenoweth's "I'm A Stranger Here Myself," "The Oldest Profession" from THE LIFE, "The Saga of Jenny" from LADY IN THE DARK, and Bernadette Peters' "I Never Thought I'd Break," among others. I still don't get how it made those connections.
