Flashback Charts
Found a cool link on another blog that sounded like fun, called Flashback Charts. Take any date, like your birthday, and click through the charts of month and day, then select the year to find the #1 song according the Billboard Charts.
The number one song on my birthday is one I cannot recall ever hearing! LOL
For fun, I checked out some other number one hits on special days, like when I got married and when each of my kids were born. Hope you have fun finding some great song memories, too.
