On Animal Crossing how do you get music in your room

To get music, you need to buy a stereo. Tom Nook sells these in his shop. Then you need music. You can listen and get these from K.K. Slider. He is in the coffee shop every Saturday night from 8:00 until 12:00. When you have the music, go to your house and tap the stereo. Tap the + button. Then select the song from K.K. Press play!
