Como Tocar Por Tu Amor

Lately I've been feeling more and more motivated to start practicing guitar. My friend has been pushing me to do it for about 5 years. He has been using my guitar, which is better than just letting it sit in the closet for those 5 years. So lately now that I've been feeling more motivated to play, I've been listening to a lot of classical music and other various acoustic songs of interest. I've always like the guitar in Por Tu Amor, by Los Alacranes, but never could find a good tutorial on it.

I found this one on youtube by a user named Tanalyss who shows how to play the main part with just 4 chords. Even a noob like me understands this video pretty well.
