I don't understand the complaints about the music in public rooms.
I tend to agree with you, but on the other hand, I do think that being able to listen to the same music as the other people in the room does enhance the experience.
If I don't like the music, I will just listen to my own, without complaint. But I do think it is rather stupid to be using a geo-locked radio station in a public room, which is the situation now in Sin Club. I like the music that station plays, but I can't listen to it unless I set my VPN to an access point in the US.
