What should contain my blog-posts? (sorry, I’m quite new in blogging world…)

Anyway, question is: should I post from time to time on the music I like or should I make a web page to gather all? Ok, nobody care … but if you have time, have a look at musicovery, it’s beautiful and fit well in my graph-oriented brain (I have a dream project called orgraphizer, but it’s still more a dream than a project).
