Which decade?
Okay, here is a list. It's what's currently on my earworm list, for the most part.
25 or 6 to 4, Chicago
Dust in the Wind, Kansas
Bridge Over Troubled Water, Simon and Garfunkel
Somewhere Over the Rainbow, Israel "IZ" Kamakawiwoʻole
Seven Bridges Road, Eagles
and as a bonus
Hurt, Johnny Cash
Tomorrow the list will probably be different.
