How To Add Lyrics To Mp3 File On Windows Media Player?

I want to add lyrics to a song so when i sync it to my phone ill get the lyrics on there. I would normally know how to do this, but at the moment im stuck using my laptop with windows 7 and i hate the media player that comes preloaded with 7. It seems this media player doesn’t have “advanced tag editor,” which is where i usually add lyrics manually on my pc.
Please tell me how to do this…Thanks!
