All kinds. You should dip your toes into every genre and experiment. This will take you out of your comfort zone. Doing this will make you better at your craft overall.
DO NOT completely abandon your sound or style of making beats because it’s probably the reason why people are buying your beats in the first place. If you build a following by selling the same type of beat, then completely abandon that, then the people that were buying from you before are less likely to buy from you now. If you completely abandon your style, then your customers may feel like you have completely abandoned them.
NOW onto what you should do. You should try to EXPAND your beats. Well, how can I do this? Upload the beats that people already like and are familiar with then every once in a while add a brand new beat to see the reactions. If the numbers are good and growing, then try to add in more beats that are like that. You can also add in some elements from what you have learned from other genres into the beats that you already make and see the public’s reaction to that.
