[intro] [verse] Woke up to the sound of nothing wrong coffee tastes like summer, radio's playing our song The kind of morning that sneaks up on you when you've been walking through the gray so long Yellow light, pouring in through the kitchen blind I'm laughing at a joke that’s not even my kind Joys resurfaced in my head for no good reason except that everything just feels so right [pre-chorus] They say it's just a chemical, serotonin in my brain makes me feel like dancing in the rain [chorus] Happiness hits like a freight train running wild through my veins Not a whisper, not a maybe— It's a shout, it's a wave crashing over me Happiness, you're electricity lighting up everything I see I forgot how bright you burn, welcome back, it's your turn [verse] Called my mama just to hear her voice She said something stupid and I'm laughing with joy We're talking nonsense for an hour straight, making plans with no debate Strangers on the sidewalk look like friends and every good ending never ends I've got this invincible feeling in my chest making feel like I’m the best [pre-chorus] They say it never lasts, that it's a temporary high but right now I'm immortal and learning how to fly [chorus] Happiness hits like a freight train running wild through my veins Not a whisper, not a maybe— It's a shout, it's a wave crashing over me Happiness, you're electricity lighting up everything I see I forgot how bright you burn, welcome back, it's your turn [bridge] Oh, happiness, happiness, I know, yeah, I know, You might leave me tomorrow and I’ll be back in my sorrow But today I’m fine, you're all mine, and I'm not letting go So, I'm gonna squeeze you until I burn this feeling of happiness into my bone When darkness comes back around, I'll remember how I felt, like a king on his throne! [piano solo] [chorus] Happiness, hits like a freight train running wild through my veins Not a whisper, not a maybe— It's a symphony, it's a fire inside of me Happiness, you're everything now, more than just a feeling for me Stay with me another day, just another day! I won't take you for granted anymore, happiness, you’re what I'm now living for!Yes, oh yes, what I'm living for, what I'm living for! Happiness!
