Are any of you familiar with the brand of small toy radio?

It plays the chorus of the songs that were popular at the time. The radio is small (maybe 3" x 3") and its has one bottom to make it play; it also has one small rectangle to put in the small thing that has the music, its like a mini CD box and it has the picture of the singer on top. The one I had was blue and i think its a toy, but Im not sure. Im sorry if this is confusing, but i dont know how to explain it...if any of you know the name or brand please tell me; thanks
