> The most important thing is just experiencing the language. You need hundreds and hundreds of hours listening to the language to really start to acquire it. Comprehension is inevitable, just optimize for time spent listening/reading
Listening with or without subtitles? I've been trying to figure out if watching content in another language with English subtitles actually helps me at all...
Nope, no subtitles in your mother language. Only your target language. It's okay if you don't understand a lot, what matters is exposing yourself to the sounds and sights of the language, and the general message of what is being conveyed ("I don't know exactly what they just said, but they seemed pissed and they said 'mierda' a lot, so maybe that means something bad").
Ideally, you'll want to focus on material where you can understand the majority of what is being said, through subtitles or just listening. If you find you can't do that, try watching something that would be easier to understand.
