I’m not 100% sure this is okay. The main artist is aussie, but it features Colombian-American artist Soltera. I don’t know the word on featured artists.

There doesn't seem to be a rule against it explicitly. However, if the aim of Lemmyvision is to share national cultures, I would think it's against that spirit.

Unfortunately this song does run afoul of an explicit rule, though, specifically the 'national languages' rule:

If the song contains vocals then it must be in (one of) the official language(s) of your choice, or a regional language of your choice.

I don't think we can reasonably claim Spanish sung by a Colombian-American artist is an official or regional language of Australia 😆
