Things You'll Need
Instructions
Transfer digital MP3 copies of music from your computer to the SD card. Make sure they are as high-quality as you can make them, to reduce the compression distortion during playback.
Insert the SD card into the appropriate slot under the small door on the front of the Wii. Make sure to press it in slowly but firmly to ensure a proper connection. Push until the card clicks into place.
Turn on the Wii and navigate to the "Photo Channel" on the main page.
Click "Change" to open the music menu, and select "SD Card." Your music will now play in its entirety.
