Why people hate bard using songs?

How about you take a look in fflogs then you'll see which one of them it is.

You shouldn't be so quick to believe everything you see on FFlogs.
FFLogs has less to do with individual player skill and more to do with how much your friends are willing to do to make you look better. The only reasonable way to get a top ranking parse is if you get to skip out on mechanics, get fed boosted cards, have others hold off so you can pad your numbers with aoe, among other things. I know some people did exactly that even to 1UP some jerks in the raiding community in their server, because they know how untrustworthy those numbers can be and how easy it is to abuse the system.
So please give me a more trustworthy answer next time.
