I am having some problems with the radio. When I search for a particular song it will usually play it once--however, when I search for that same song again it will almost always play a different song usually, but not always, by the same artist. Lets say (just for example) I want to play "feel this moment by Pitbull," it will play it once, then if I search for it again the next day it will say "Feel this moment radio" but play a different song, usually by Pitbull. Is there some guide to proper radio usage because right now its not making a ton of sense.
