"Native Tongue", by Mo'Ju (formerly known as "Mojo Juju") sprung to mind instantly when I saw the side theme. It's not performed in a native language, but the song itself is about the subject of colonisation and its effect on the gentrification and destruction of language, specifically Indigenous language In terms of Indigenous artists who are performing in language, Yolngu man Baker Boy might be one of the most prominent at present. "Meditjin" is a banger, with a video filmed in the National Gallery of Victoria, that I've thought about sending it to PJSC before. I have another entry lined up already for this round so consider this your invitation if you're still looking for something! "Marryuna" is probably his best known song, with a big hook and a 90s vibe. For something a little slower paced, perhaps try Emily Wurramara's "Ngarrikwujeyinama", a song in the Anindilyakwa language which relates to the community's pushback to mining enterprises in the Gulf of Carpentaria and the desire to protect the seabed and cultural song lines. I would also second the Electric Fields recommendation, and also suggest investigating other Indigenous artists like Kee'ahn, Thelma Plum, erstwhile PJ Retro contender Christine Anu and of course Jessica Mauboy!
