One question...
How do you figured out the position of each song?
Do you have a specific percentage of ponderation? (BB Hot 100, Sales, Lastfm Plays ... etc)

Well I have a formula that I learned while studying marketing of "how to calculate charts".. so, it is something like this:
I count EACH countdown that has been updated on the tracked week, so I see each songs that a person likes, and in what positions they have it. I count each song, so if the chart is a "Top 40", Top 30, Top 15 or whatever, I count each song, but obviosly a lot of them don't even make it to the 300th position XD.
So depending in the position each person have a song I give them points, then over last.fm I see how many people listened to a song on the week and I use that number as a population sample, so if 76 people of 260 on the group listened to a song it's obvious that at least 1,026+ ATRLers listened to the song, so I gave them points depending of how many ATRLer listened to it.
The I take the Billboard Hot 100 positions and gave the chart those points, right now it's only about a 10% of the complete tally, so it's more considered as a "Bonus Points".
Popularity is really different, I check ATRL at least once a day, and I always check what new threads are made, and what artist is being mentioned the most, so I gave them those popularity points, so I tracked each chart from each Tuesday to Monday, so right now Madonna is being mentioned a lot with her song "Give Me All Your Lovin'", so that song wll have some popularity pounts, tho Popularity points are about 1% of the total tally which is... really nothing.. tho they can make a change if a song has 24% and other has 24.01% points, so the song with 24% can reach to 24.02% and take a taller position that the one with 24.01% that wasn't popular this week.
Was I clear?? or did I confuse you XD
