Words to Spanish Songs

I downloaded tuneWiki onto my iPod touch, and it is great! I have some songs that are in Spanish in my playlist, and this app will show me the words to the songs in Spanish, and actually scroll the words as the song is playing! And if that is not enough, you can listen to radio stations from the internet and it will pull in the lyrics to those songs too (if they are available)! What a great way to learn Spanish!
