Sir before K-POP there is Canto-Pop and Mando-pop with Teresa Cheng.
Sir If I may regarding song artist the present Chinese singers tramp the Collective West big time (I used to be a big fan of western music BUT no more), you're right about the obscurity because of language. BUT if you have the time and a music connoisseur please check the following Chinese artist and enjoy their music.

Hua Chen yu
Zhou Shen

Most people are forced to only like those who their media orders them to like. Its a sad state of existence.
Chinese are free to choose among the entire media market. Chinese stars organically rise up among Bilibili casters and are chosen by the people. A very different model than the top down command media that many outside China are used to.
@emblem21 brought up a good example, Hanser. She has 4M+ followers on bilibili and is a VA for Honkai Star Rail. Was she hand picked by the corporations or media? No.
I also follow 多多poi, 泠鸢yousa, 西瓜君, SING, etc.
20M+ view music video from SING:

Both Japanese singers have their own bilibili channels, that's how much emphasis they place on the Chinese market.
