So I recently started using my 3Ds as an MP3 player, because it's honestly perfect. No ads, easy to import my music as simple mp3's, and the mixing board is amazing.
However, I see that there's a space for metadata for the music files (see image), including what I believe to be the artist, length of the track, and possibly one or two other bits. How can I edit this metadata? What kind of program do I need?? Please ping me with any info
