Validity of Current Music Chart systems

The news that the cast of "Glee" have recently passed the Beatles for most entries on the Billboard Hot 100 singles charts, to now sit at number TWO on the ALL-TIME list of Hot 100 singles entries, triggered this thread. The cast of "Glee" have been recording for a total of one year and seven months, and, with another four charting songs, will pass Elvis Presley as the ALL-TIME leader of Hot 100 entries in American music history, with 106 individual chart entries.
Does the current system of including downloads and other digital recordings, mean that the charts are becoming virtually irrelevant when judging music quality and output? I find it staggering and frankly, rather disturbing, that a group like this will now be recognised, in offical circles, as the best chart act of all time, when compared with the likes of Elvis, James Brown (the previous number two on the list) and the Beatles. This becomes particularly relevant when considering that all but 14 of these 106 entries spent only ONE week in the chart.
Throughout much of the time of chart history, the relative price of a single - compared on a percentage of weekly wage - was a lot higher than it is now, and had far less mediums for sale, primarily being vinyl. Now, for 99 cents or so, a song can be downloaded and recognising toward calculations for charts. It can mean that, as seen in the United Kingdom in 2009, an influential group can start a campaign to manipulate the chart to a degree (with Rage Against The Machine scoring the coveted Christmas number one spot with "Killing In The Name Of", a song released originally in 1993), and can render previous chart records meaningless.
How relevant, therefore, are charts nowadays? When I was a kid, I often used to get up at 5.30am to watch the Rage Top 50 all the way through, working out what number one would be. Reaching number one (or indeed, number 50) used to be a real achievement for an act then. It seems much less now
