You were cleaning out your room; getting unnecessary clutter out of the place, sorting an organizing things and places that need it, etc. Then one of your favorite songs come on! You can't help but sing along to it.
"Every girl from here to Soho, Loves to tell me things I don't know, Beautiful and smart, and not good for me. At all. All your boyfriends go to film school, Nathan was in plays in high school, Me, I'm gonna play the imbecile, oh. Who keeps choosing you even though you're bipolar and you're selfish. I hate you, ah! Everyone is better than me, I think Everyone is better than, better than me Everyone is better than, better than me Hey, hey, oh, hey!"
Yeah, you attracted some attention from your classmates with the song having a higher volume than the rest, the mildly concerning topic of it, and the fact you were enjoying it and singing along.
