Replying to Help with blog platform

so i want to start a blog and i want it to be simple and free, but i would like it to be organized into subjects, for instance i want like a music video page, a photo page, a short film page, and i want each one to be a seperate blog/page rather than have one messy page with all of them thrown together randomly by date, ive tried using blogger and it will let me have seperate pages but wont let me have blogs on each page, any help with a platform that I can easily organize this on?
