To activate StreetPass for the 3DS Sound app, tap on the StreetPass button on the lower left of the touch screen. The lower part of the screen will have a button that says StreetPass Off. Tap that and then tap the On button and Confirm to turn StreetPass on.

This requires that you have at least one song in the StreetPass playlist. To achieve this, first you must put a song on your SD card from another device, such as a computer. To do this, insert your SD card into an SD card slot if your computer has one or a card reader peripheral reader otherwise. Then the SD card should appear as a drive in your computer, and you can copy files to it the same way you can with a flash drive or generally moving files around in your file system browser. The music files have to be of one of these four formats: .mp3, .m4a, .mp4, or .3gp and they have to be in a folder.

Then put the SD card back in the 3DS and open the Sound app. In the app, navigate through the folders to a song and select it. There will be a button on the bottom right that says Add..., which you can click to add the song to a playlist. Once you add a song to the StreetPass playlist, the option to activate StreetPass will become available.

    So how do I get another song from a computer to my SD card? Apr 24, 2012 at 22:36
  • I don't understand your question. When you say "another" do you mean that you already have a song on your SD card? Apr 24, 2012 at 22:42

    No.. I want to know how to get a song from a computer, rather than the ones I have already recorded from my 3ds. Apr 25, 2012 at 22:05

    Oh no!!! My computer does not have an SD card slot!!! Apr 25, 2012 at 23:07

Just look for any songs on your computer anywhere. Left-click the mouse and then press save as, name it, find it, and move it to the SD card. There are sometimes SD card slots on the tower of a computer.
