Am I the only one who thinks songs like Sunrise~Lia~, glitter, NL etc are just purely "feelgood"-songs and not trying to convince anyone anything...? Just because they don't have anything "deeper" than just being happy and wishing for good things in the lyrics doesn't mean they're less meaningful. Most of you are probably gonna lol hard but I have actually cried while listening to glitter
To me there's something bittersweet/mellow about that song, and it just happened to fit very well to my feelings atm. But yeah even in those songs I actually do feel the emotion in her voice.
