I've never actually looked at Erin's challenge before. I like the advanced skits, they're sort of my speed. I listen to more advanced stuff but its nice to feel like I'm actually totally sure of whats going on. I think the best option is always jdramas with subtitles, exspecially at such an advanced level as 37k words. I probably know about 2-3k (I'm not entirely sure... there's a lot of stuff I know just from repitious listening alone and not anki) and I can follow the story of a jdrama that way. Really, context, setting, facial expressions, tone and just knowing the premise of the show can really help you work out words. And people's diffferent accents, level of slurriness etc is something you really have to learn to deal with because that's what speaking to people is like. I also like to listen to really casual podcasts, which get much more slurry and slangy than any j-drama. I think though, some dramas will be worse than others. Somehow I had a great problem with GTO because it seemed way faster and slurrier than nay modern jdrama for some reason. So I gave up on that one. I feel like anime characters have clearer voices but jdrama characters have real voices and more regular ways of speaking. So I would generally say a day-to-day sort of drama is best. News and stuff requires such diverse specialist language and not as much auxilliary clues. Plus nobody speaks like a news person.
