The way iTunes works, you have to manually add files to is playlists through the app, and then those songs are in its playlists and from there you can play the song all you want. I'm looking for an app that doesn't have pre-made playlists, but instead dynamically uses its music folder as a playlist. So you can drop files in the music folder from across a network, and that the song will be right in rotation. Anyone know of any apps like this?
