It's me, the critical anon. I've returned to see how things are going.
Seems you're struggling to find idols...
Honestly, the best idols/musicians are all JP chuubas at the moment. I have a few small Western indies I'm keeping an eye on, but things aren't looking great. I won't mention them unless they become more active.
If you want some to check out that are better known, I reccomend Prism Project which has a fantastic roster of singers and musicians, especially Shiki who is my personal favorite from them:

https://youtube.com/@isla_kawaiiAmiya Aranha is also lovely, very nice voice, has some covers:

Easily one of my personal favorites is NiceEggy, a seiso and charming egg themed opera idol vtuber, who has some amazing covers on YT, but streams primarily on Twitch:
https://www.twitch.tv/niceeggy?sr=aZephyrianna, a heavy metal idol vtuber with lots of covers and a few originals, also does music production streams, has an amazing voice, very skilled:
https://youtube.com/@ZephyriannaChThinkerbella, who does karaoke fairly often and has covers on YT:
https://www.twitch.tv/thinkerbella?sr=aTiredSquid is also good, though she focuses more on variety content, but she still has a great voice and is a big fan of Vocaloid:
https://www.twitch.tv/tiredsquidd?sr=aThere are some others, I'll come back to post them if I recall. It would be nice to be able to post some JPs as well, but I suppose the vsinger thread has that covered mostly.
In keeping with tradition, I'll give another piece of advice. When looking for a quality idol vtuber, a good check is to see what sorts of tangential topics they are interested in, like hobbies or music or what have you. The best ones are often very "weebcore", and the more knowledgable, the better idol you will find. Idols are also focused on self improvement as well, so that's good to keep an eye out for.
I see some recommendations here that I would warn you to steer clear of. I won't name names, because being an anti will only hurt my credibility here, so I'll let you use your brain and just remind you again to stay critical and observant.
Enjoy your idols.
