The only way to do this sort of thing is to pick a week and get LOADS of fans involved, from lots of different forums including Backstage. And also make sure that the track is downloaded from a site which definitely counts for the charts.
It may be an idea to look at a week when there isnt many big new singles released and target that one.
I dont know the rules of eligibility, but if the record company were to release a slightly different version, even a live version, then this would count, as well as giving us something new.
Maybe we should badger the record company to give us Prayer Live from Giants or Milton Keynes or something??
Also Prayer is down to No.118 in the downloads chart at the mo
