It's not new news.But have you ever had one of those songs that is just contagiously catchy get stuck in your head? I'm not talking about "this is the song that gets on everybody's nerves" ... but a ... song that is much more adult?I burst out randomly in the middle of a maths test with "Bad Kids" by the Black Lips. Yeah. That was awkward. But at least my teacher's chill and laughed it off. Thank god.
