you have two options
1) Try and figure out what people like and then try and write stuff to make those people happy even if it''s not what you'd normally choose to do
2) Write what makes you happy and hope some other people like it but if they don't, oh well you had fun creating music and bringing it to fruition
Either way you'll never get rich and famous doing it unless you are unbelievably lucky and have big boobies like Katy Perry (but not if your a man. I'd imagine the fan market for Katy Perry sized man boobies is not large)
with that in mind I went for option 2. YMMV
