I don't think I'll do a decade one. I don't have enough data from post-2006 to compile one. This year I'll just once again post my top 100 most played artists/songs on Last.fm and hope for the best. Next year is when I'll actually compile it based on my top 40 chart.
I do have plans to mark the end of the 00s, though. Maybe a few honorable mentions every so often in the thread from years back.
First I will finish my Top 100 from 2008, they close the forum before i get to finish
I'm ready with my Top 100 of the Decade and for 2009 I will do first for every genre I like (Rock, Pop, R&B, Hip-Hop) and then my "Hot 100" of the year all in one thread!
I'll be doing both a year-end chart for 2009 and a decade-end chart for the 2000's (my first official decade-end chart as i didn't do one of the 90's). Can't wait for it
