You're so funny 😂 you're getting the names right though! Mapa is arguably their biggest song (the most viral is Gento ofc) sitting at 110+ millions views on the lyric video, stands for Mama and Papa and talks about parents/guardians. I recommend the First Take perfomance if you are interested in the vocal aspect. I also recommend watching Casual Chuck fan made docu series on them to get to know their story. +their performances on Rappler and Wish Bus are a staple in their career as well.
