There are several radio stations in Hong Kong that broadcast in English, and there should be music programs in them, namely Radio Television Hong Kong 3 (AM567), English Channel of Hong Kong Commercial Radio (AM864) and News Channel of Hong Kong New Town (AM144). I hope I can solve your problem.

PS, if you don't understand English, there is a program that broadcasts English songs, that is, the tranquil feelings of Radio Television Hong Kong No.1 (FM92.6-FM94.4, Shenzhen FM93.2 or FM93.4) (8: pm to 9: pm), but it is hosted in Cantonese.
