Number one songs 5 seconds at a time (give or take) in two parts. The first part was my favorite, naturally, and had almost nothing I didn’t recognize or couldn’t name readily. There are clearly some groups who got shortchanged in the number one hits department, but then only a song at a time can be there, and weird things happen. The second part goes to 1992, and has large swaths I just didn’t recognize.
The other funny thing is when I do know them, but find myself surprised that they were that long ago, or that one that comes earlier falls before one I’d have placed earlier in my perception of memory. Worth a listen.
