My favourit Dj and producer is Avicii ( Tim Bergling ) . He is very famous man . He has write more the fifty song . He has every month fastival ( party ) . He is now try to create new song . All his days always busy , because every day try to write music with new singer and he hasn't time for break. Today we can find him in web-site , magazine , Tv . I thing he is very very cool producer and dj . He has a lot of fanats . You can find other cool dj , but for me Avicii the best producer . It's my mind . Two days ago he has festival and on this festival was 500.000 people .
