I have formed my favourite stations based on my riders personal tastes. I often ask riders what kind of music do they like and search for it. Over time a nice variety is formed. Music often keeps the mood upbeat and happy. But do be aware that some people prefer silence. If I may use this example, female Asian international students who ordinarily won't say a word to me will suddenly become my bestie if I play K-pop (Korean), in particular Big-Bang are in right now. Chinese girls love it too. Japanese and Korean music culture has strong support across Asia. Then for Chinese, you have someone like Jay Chou (you may remember he played alongside Seth Rogen in The Green Hornet). Careful not to play him to older Chinese men though who may care more about the Taiwan Vs China sovereignty issue. On a side note, since advertisements came back at the start of 2017, do you get solely American ads from the USA?
