(s)Hit40UK has finally been scrapped, but it doesn't sound like its replacement will be much better.
The chart is now based on iTunes only. So I do wonder, why don't they just call it the iTunes Chart?
Also, any songs downloaded before 6PM on Sunday will still be counted in this weeks chart, so you can influence the chart whilst it is on.
I don't really pay any attention to the charts any more as most of the music I like doesn't do very well in the charts. I will certainly be ignoring this one though if I want any statistics.
