This week’s chart is dominated by the effects of the Glastonbury Festival, that much loved annual event in which London media types get to tell us how they went to a field and saw some mud.  Personally, I’ve never been that keen on festivals – I went to T in the Park a few times back when I did student radio, but even then I kind of saw it as a massively inconvenient trek to see bands who’d usually have been better in a proper venue.

But the festival circuit is an established part of the UK calendar, and Glastonbury is the established top festival, which means it gets tons of radio and TV coverage from the BBC (particularly today when there are acres of space to fill on the digital channels).

Jason Derulo’s “Don’t Wanna Go Home” is still at number 1.  But the highest new entry at number 3 is “Best Thing I Never Had” by Beyonce, who was one of this year’s headline acts.

Now, this is the second single from her new album “4”, which enters the album chart at number 1 this week.  It’s also a pretty good song in its own right (in a lighter-waving kind of way).  So it would have entered high anyway.  But look further down the chart, and you’ll see “Run The World (Girls)” rebounding from 39 to 23, and a seemingly anomalous re-entry at 33 for her 2006 single “Irreplaceable”.  That one’s because her Glastonbury performance of the song was released as a charity download.  But the chart no longer distinguishes between different versions of a song by the same artist.

Also headlining were Coldplay, and their last single “Every Teardrop is a Waterfall” – which had swandived out of the top 40 after only three weeks – rebounds to number 10.  They’ve got a live single out too, which results in “In My Place” re-appearing at 40.  Incidentally, “Teardrop” now has a proper video, where we can enjoy Chris Martin rocking his new “funky catalogue model” look.

There was also a third Glastonbury live download – “I Will Follow” by U2.  Somewhat remarkably, it failed to make the top 75.

All that leaves only two other acts releasing singles this week – “Dirty Dancer” by Enrique Iglesias featuring Usher at number 28, and “Next 2 You” by Chris Brown featuring Justin Bieber at number 39.  (That one’s going to climb.)

Neither of them is particularly memorable, though the Chris Brown single does have a remarkably overblown video entirely at odds with the music it’s meant to be promoting.  So instead, here’s Coldplay’s best video by a mile – “Life In Technicolor II”.
