I'm glad to hear Vietnamese people can now use Spotify as well! :)
About which genre is the best, it's hard to say. I guess it's best to just listen to music you like. :) The Discover Weekly will try and help you by finding songs similar to those you've listened to a lot, saved, put into playlists. It will give you 30 songs every week. If you find something great in there, make sure you save it or put it into your own playlist, because Discover Weekly will replace its content every Monday!
Edit: You may give a sample of what songs you like so far. Maybe I or someone else are able to give a suitable playlist :)
If you have more questions, I'm here to help!
