The vocal arrangement has a hip hop feel to it. Most pop songs have very few lyrics and those lyrics are usually repeated to the point where you want to shoot yourself in the head (Can't Feel My Face comes to mind). Alessia spits lyrics like Really I would rather be at home all by myself / Not in this room with people who don't even / Care about my well being / I don't dance, don't ask / I don't need a boyfriend / So you can go back / Please enjoy your party I'll be here. It's hard not to dig this cut by this new artist.
If you like this then check out her other cuts Outlaws and I'm Yours. They're catchy love songs and worthy of a listen. You're welcome.
