LBT, Digital Downloads and Chart Rules...?

[big screen satellite]

any idea how many copies LBT has sold, and if so how much if any impact does it have on the UK download chart...

i tried looking up the rules on the official charts company website, and they haven't got any 'rules' as yet...so i don't know if LBT even qualifies...

but, if its sold enough would this count in a download chart, and if so have Underworld registered it, and do they care...??

just wondering, i doubt its selling as many as Madonna for example, but who knows, they may be making a dent somewhere... and what about Japan, does Japan have download charts, other than the ones on ITunes - this (JAL to Tokyo) must be selling quite well to get it to the top spot in the ITunes download chart over there...

any one official care to comment...or do i have to find out this info on Teletext somewhere
