Makoto and Akira are still taking song requests for their 10K subs karaoke stream. I don't know how many songs they plan on singing but there's still 40 hours left before the stream, so if there's a song or songs you want to hear them sing, you can either reply to the tweet with your request/s or you can type the requests on their discord:

Maybe there's a song sung by a male singer that you're curious to hear what it would sound like if sung by girls. As always, there's no guarantee they'll sing your request so the trick is to send them multiple songs so you have a better chance of getting at least one of them sung. You could also try explaining why a particular song request is very important to you and that's why you want hear them sing it.
