To accompany me at night

When I close my eyes at night, I am having some hard time to sleep. My sister says, I have and insomnia. This is the reason I always play the radio and listening to music till I fall asleep. But when the sister got married, I did not able to play the radio again because she brought it with her. Good thing my cellphone does have a radio feature. I just played it at night the listening to music. The problem is that I have to charge my phone everyday because the battery is exhausted when I wake up in the morning. I feel so pity for my phone that is why I want to buy new radio soon. I am searching of what would be the best radio to buy when I saw this kaossilator musicians friend. I like it because it is so cute and high technology. I know now what to buy to accompany me at night.
