How do you feel when you listen to J-lo's "On the floor"?

ok, basically when I heard this song I didn't know who it was, heard
it once and HAD TO FIND IT...but the reaction I get when J-los chorus
comes up is almost weird. Is it just me or does the la la la la la la
la la give a depressing vibe? it might be the sample, but for some
reason this song hits me hard. It depresses me, makes me think, but I
cant stop listening to it...opinions?
