IF anything ya'll are forgeting the simple fact that radio takes into account and not just sales.
I think 58 is great considering a 5m AI and sales that climbed but not as the sales week began.
Next week it can easilly go to Top 30 but don't expect it to blow off with little radio help..It will need to out sell way more than that.
Take a look at Ke$ha's Sleazy remix which peaked at 8 or so at iTunes and how it charted.
She will gain steam at radios really quickly and got almost a week to get higher AI to help her but for now I don't see her go over 12m AI which is not alot and 1m = 1k sales kinda in the BB Hot 100.
WDKY has won the song battle on my local radio station (KDWB) 5 days in a row. It has been retired from the contest and will now be put into regular rotation.
