How do you get music on your radio on Animal Crossing

To get music on your radio, stereo, or CD player is to go to the museum on Saturday night at 8:30. At the museum there's a cafe this cafe has a stage on the stage theres a dude K.K . Get K.K to sing his song after he has finished the song you will find the song is in your pocket. Next go to your hose click on your radio, stereo, or CD player and press the plus thing and click on your song and will put it on your radio, stereo, or CD player.
Hope that helped.
