Hi everyone!
So what do you usually listen to while you’re burning through your ever growing pile of reviews? I’m getting to the point now where if I skip a day, I return to 250+ reviews waiting for me. Just found one of those generic “Lofi hip hop beats to study to” playlists and found this works nicely for me.
What music/sounds help you concentrate?
If I listen to anything it will often be a classical music playlist.
I listen to my keyboard followed by internally voiced swear words because I type too fast, or press enter after typing the japanese when it asked for meaning.
The sound of silence.
The sound of the vocab.
Oh man I know your pain. The amount of times I’ve been like “Oh this is easy…” typed too quickly and ended up looking at “Ichi” or something written out on a red background… so painful when it’s a super obvious one.
Japanese music mostly, but also depending on the mood.
Sing along, too, for a challenge. 
I like listening to the vocab, it helps my retention. I have a script that plays the reading for reading and meaning questions.
For kanji / radicals, this times 百万:
I’ve been the no scripts guy for a long time, but y’all should get the WaniKani Override script.
It lets you ignore typos, or any sort of mistakes you want.
(Mostly answering correctly, but not exactly what WaniKani wanted.) (Don’t abuse it, tho.)
I listen to the native speaker and repeat what she said.
I could hear the silence and cries and tears of suffering and dying patients and their families when I do my reviews at the hospital.
I could hear anything that Japanese speakers said on Japanese TV I watch while doing my reviews.
I could hear the nature and birds chirping, a lot, and sounds of water when I do my lessons. Sometimes that selfish cat’s mew too.
If you ask me which one I mostly hear, the second one. And the varieties of the second one. Like yelling patients’ families who were furious and heard like they lost control of what they did despite other patients’ existence. The sounds of people’s / nurses’ steps on the corridor.
The sound of Japanese people slurping instant noodles.
That sounds like some interesting white noise.
ASMR 
Nothing. IMO it’s a distraction and humans are scientifically proven to be bad at multitasking.
Usually I just listen to the vocab audio. But I do have some favorite tracks to help getting into different concentration “moods”:
I listen to my Spotify playlist, Sunny Windowpane, which is just a bunch of indie J-rock. I dunno why, but for some reason it really helps me relax–and it’s super fun when I recognize a word in the song that I just learned on WaniKani!
I’d recommend illion, Kenshi Yonezu, or sasanomoly. 
If you want something to get your blood pumping and keep you awake, check out The Prophet Said Survive (so emo :'D).
Listening to Nujabes as we speak.
Usually video game OSTs, but some words I get as lessons I randomly remember from anime openings I learned phonetically years ago, and then I end up playing the corresponding song when the word pops up in reviews
Truly. but if there is enough background noise to be distracting, I usually choose some kind of video game background music because its usually composed to provide music without distracting, (40 ~ 60 BPM) Classical is also good for this, but I find it has too many “highlights”, since it’s usually intended to be performed.
Depends. Sometimes its silence. Sometimes its whatever music I’m in the mood for at the time. A few minutes ago it was the baseball game my team is currently losing ( although hopefully not for long). I’m more likely to put something on if I have a lot of reviews. Tonight I only had a handful, though.
