Tagging your music files allows you to add information about the song, the artist, and album art to the mp3 files. This way, when someone opens your mp3 file to listen to it, they will be able to know more about you as an artist and to find more of your music.
Music Supervisors also require that your songs are tagged with meta data (descriptive data about the song).
MP3Tag is a free utility you can use to tag your mp3 files. Using mp3tag you can tag multiple files at one time – convenient for tagging data that applies to multiple songs, like, all songs in an album, your name as an artist, your website in the comments, etc.
Here is a short tutorial video of mp3 tag.

This is useful information, thank you. I have found that adding this type of informaition to MP3 files is a bit hit and miss so I’ll have a go with the app you recommend. It drives me mad when I download MP3s that don’t have proper information associated with them as you can never figure out which is which in the player.
