Identify the song for which you want lyrics. But even if you can't remember the title, you still may be able to find it. Go to the Songtapper website (see Resources). You can tap the space bar along with the beat and the website will list possible song titles. Songtapper is more accurate if you tap for a longer period of time.
Check Reggaeton Online or the Reggaeton Lyrics website. Input the title to find the song lyrics. You can search by song title, album or the artist. The Reggaeton Online website also features song clips. You can also check the Reggaeton website, but you must register, which is free, before you can use this website.
Verify that the lyrics are correct. Check the lyrics against multiple websites to make sure that are absolutely accurate. You'll see that the lyrics will occasionally need refining.
Translate the lyrics, if needed. The song lyrics may be in Spanish. Use an online translator to translate the lyrics into a different language.
