I combined the 4 song spreadsheets; 2000s, 2007, 8, & 9, into 1 master spreadsheet to see how the songs would stack up.

I weighted 2009 slightly heavier than 2008, and 2008 slightly heavier than 2007. Only the top 50 songs from each EoY list were kept, and songs with only 1 listing were removed. I kept the EoD sheet as is.
