Apparently my music knowledge is lacking. I did not recognise a very famous song/artist at a wedding recently. I am very bad with music but usually I recognise a song even if I can't figure out who is singing or what it's called. DH reckons "everyone" knows it, it was always on when we were young. He's a bit older than me and grew up in a different country so I think we listened to different things. (Plus I wasn't allowed to listen to music in my parents house.)
So, in an effort to be more cultured I'm asking which pieces of music or artists you consider "everyone" should recognise and I'll make myself an educational playlist!
