You can do what you want to do in the following way:
>> Open Windows Media Player, go over to the Library tab and select the song for which you want the name to be displayed. (If you cannot see any songs, hit F3 and insert your folder and then let it scan)
>> Once you have selected your song, right click on it and select Advanced Tag Editor. This has to be done inside the Library.
>> Now go over to the Lyrics tab.
>> Click on the Add button on the right, and select any English language or any language and then type in your name in the Text section.
>> You can keep this text moving by using the advanced feature 'Synchronized Lyrics'.
>> Hit Apply after you're done and then OK.
>> Now Play it and go over to the Now Playing tab and see if your name came or not.
>> While doing the above you should make sure that no song is playing in the background. Stop the song and then follow the above steps.
>> To remove the name first stop the song from playing (not Pause, only Stop), then rt click>Advanced Tag Editor>Lyrics tab and select the first lyrics section and hit Delete.
>> Apply then OK.
Hope this helped.
