Yesss, h34! Embrace the joys of minority-language-song addiction!
Pipil, or Nawat as its speakers call it, is a moribund variety of Nahuatl spoken in El Salvador, though there are people who learn it as a second language and there are apparently quite a few online resources for learning it. It's an Eastern Peripheral Nahuatl variety, which means it's closely related to Sierra Puebla Nahuatl and (perhaps) Tehuacan-Zongolica Nahuatl. This is a song in Pipil called "Ne nawat shuchikisa," meaning something like 'Nawat is flourishing':https://www.youtube.com/watch?v=bIH7_yY8YM0
