  Some portable terminals include a random playback function for randomly selecting a music to be played back from among downloaded music and playing back the randomly selected music. This random playback function accepts surprising (surprise) and unknown (freshness) playback order. However, since the downloaded music is originally downloaded according to the user's intention, the unexpectedness remains within a certain range and the unknown is extremely small. The range of user's music selection is often limited to their own hobbies and areas of interest, and the user inevitably listens only to songs of his favorite genre.

Therefore, there is a demand for a method that can provide a user with a mobile terminal with a musical piece that is unexpected or unknown. However, the songs listed in the song order list by song request order and song genre are often popular songs or trendy songs or familiar songs of your favorite genre. And often lacks the ambiguity to download. Patent Document 1 discloses a music playback method that provides a list of songs of local songs in the area according to the current position. There is a drawback that it is necessary to attach regional information by hand.
