How to Add an Artist to an MP3 Fileby James Stone
Adding in the artist who created the music for an MP3 file is either done manually on the Details menu or automatically using Windows Media Player. Album information automatically updates each time you start Windows Media Player. Windows Media Player connects to the Internet to download the latest album information for each MP3 file in your library.
Click the "Start" button and then the "Music" link.
Right-click on a "MP3" file, then select "Properties."
Click the "Details" tab, then click inside the "Album Artist" field under the Media section.
Type in the name of the MP3's artist and any other information you wish to add.
Click the "OK" button to apply the changes and close the dialog box.
