Hello. I am wondering if there any music apps (besides Pandora, Last.fm, imeem, Slacker, etc.) that will play the song that I want it to? For example, say I want to listen to Empire State of Mind by Jay-Z, what app can I go to and type in "Empire State of Mind" and listen to that song, instead of "similar songs"? All of these Pandora, Slacker, etc apps are exactly the same. Why can't I listen to the song I want instead of similar songs? I just don't get it.
