if i'm in a bar and a good song comes on i will always say something, but even if i'm home alone and a good song comes on in my headphones - let the universe know!
(it just happened to me with Sinner by The Last Dinner Party)
It’s not always needed but you always know when it’s the right time. I do it every now and then and it makes me laugh a little. It’s never The same song. One day it’ll be My Heart Will Go On then the next day it’ll be Pharrell’s chorus on Beautiful.
