It depends. Like Fribby said, it's kind of hard to say. It often makes me think about things that will make me feel down, but it depends on the song, I guess.
i guess like any music it really depends on my mood to begin with...but on the whole it makes me feel happy, some people say its like angry people music (in my school) but its not, just a different expression of possibly the same feelings...
I cant decide. It all depeands on the song. If its something like faint then yeah Im all happy and jumping on the couch freaking out my freinds but if its something like creep(STP) than im just againt the wall thinking about the lyrics making me sad.
