I like your list. (I think you meant “by year”.)
Thanks. And yes, of course, I did.
I recognize you chose the top 7 hits of each year as an impartial starting point... and that was a very sensible decision! The tough part is that is that Billboard’s year-end ranking methodology often promoted the blandest songs. Actual sales, weeks at the top, etc., were actually not considered as much as market penetration. If you ever try doing this again (next year?), now that you’re identified the weeklings, maybe you could nominate additions to the competition? It was fun, and I appreciate your effort.
