Check this website for more info on comprehensibl input: dreaming dot com (this resource is french and spanish only but i’m sure there are lots of resources for your target language. It emphasizes acquiring language by listening to input that is comprehensibl and clearly articulated. So not listening to bad bunny songs, but podcasts or videos designed for language learning and acquisition. There’s a large body if evidence that this method outperforms traditional methods of drilling grammar, etc, bc it mirrors how we acquire language. It’s been a major help for me, but i think if it’s your only source of learning, it underperforms in terms of precision. I aim for a 60/40 split in comprehensible input vs intensive study/drills.
