"For now, the Radio feature will not be available for U.S. users."
"The radio feature will eventually be available. However, I can't say exactly when that will be. Be reminded, that Spotify is not chiefly a radio service. The lack of a radio feature for the time being is a factor of licensing agreements with the rights holders but it will eventually be available.
So the lack of a radio feature in no way limits your ability to search for and play the song of your choice. Just to be clear, when the time comes, the absence of a radio feature will be available for free as well as Premium users, as it is not typically one of the main benefits of a Premium subscription. "
Is there a way to play a personalized station? I am a fan of having my music selected for me.
