A slightly busier chart than we’ve seen in recent weeks, but six new entries is still fairly tame by the standards of recent years.  Perhaps due to the streaming data slowing things down?

39.  Jessie J – “Flashlight”

This is from the soundtrack to Pitch Perfect 2.  Given that it’s had a month of promotion, a version of the song is used prominently in the film, and it has co-writing credits for both Sam Smith and Sia (though not Jessie J herself), it’s a pretty weak debut position.  And indeed, it does sound like something Sam Smith or Sia might write and think, no, maybe not for my album.  It was at 27 in the midweeks, which would normally indicate that sales tailed off drastically, but oddly today’s midweeks have it climbing to 14, so don’t write it off just yet.

36.  Sheppard – “Geronimo”

This was a big hit in Australia last year, and understandably enough, but it seems set to make a one-week appearance at the bottom end of the chart before vanishing.  Sheppard are an indie pop outfit from Brisbane, named after the three sibling members’ surname.

There are two completely different videos for the song.  The one above is the Australian original, but there’s also a more conventional performance video which YouTube lists as the “international version”.  And for masochists, there’s also a clumsy re-edit of that video to go with the entirely redundant Benny Bennassi remix.

35.  Ne-Yo featuring Juicy J – “She Knows”

Well, nobody could call that a subtle video, could they?  Climbs to 24 in the midweeks, which still isn’t great by Ne-Yo’s standards.

24.  Andie Case – “Want to Want Me / I Want You To Want Me Mashup”

An oddity.  As advertised, this is a mash-up cover version.  “Want to Want Me” is a song from Jason DeRulo’s upcoming album, which didn’t come out in this country until Monday – and thus makes its first appearance on the UK chart in the form of an acoustic cover version which a singer from Seattle posted on YouTube.  It’s not a cash-in – the Derulo track came out in March in the US, and has already been a top ten hit in most of the rest of Europe.  But this is the UK, and we do things differently here…  As for “I Want You To Want Me”, that’s the Cheap Trick song which got to number 29 in 1979.

It’s a genuine cover, not a clone, but something of a novelty – the record is indeed the soundtrack of the YouTube video above, recorded in a car.

12.  Ella Eyre – “Together”

Ella Eyre had a number 1 in 2013 as the guest singer on Rudimental’s “Waiting All Night”, but hasn’t made it back into the top ten since then.  This was at 6 in the midweeks, but it can’t sustain it.  The record is very much school-of-Rudimental (funny, that), and the video seems to be trying to shoehorn a love song into a “gang of friends on holiday” schtick.

4.  Taylor Swift featuring Kendrick Lamar – “Bad Blood”

A nice, subtle video, then.  Lots of guest appearances in there – among other things, that’s Selena Gomez as the ex-partner, and cameos from the likes of Hayley Williams, Ellie Goulding, Jessica Alba and Cindy Crawford.

This is the single version of a track from last year’s “1989” album, reworked with added Kendrick Lamar.  Usually when an album track sprouts a guest rapper on its single release, it means that he’s going to pop up for the middle eight, but here he actually gets the first two verses and relegates Swift to the chorus of her own song.

Swift has openly stated that the song is about another female star who she fell out, apparently after some vaguely-specified transgression coupled with what Swift sees as an attempt to sabotage her tour by hiring key personnel out from under her.  She hasn’t actually named who she has in mind, but it doesn’t take a genius to figure out that the likely suspect is Katy Perry, who poached several of Swift’s backing dancers in the course of her last tour.

Kendrick Lamar has never previously got above 15 on the singles chart, though his current album “To Pimp A Butterfly” did get to number 1.  This was the second-biggest seller of the week, but of course, Taylor Swift doesn’t do streaming, so the new chart rules work against her.

1.  OMI – “Cheerleader”

That’s four weeks, and it would have been number 1 with or without streams.  It’s the third number one to manage four weeks in this unusually slow year (the others were “Uptown Funk” and “Love Me Like You Do”).  It won’t manage five, but hey, who’s complaining.

Since “Cheerleader” is selling in a heavily remixed form from the pop-reggae original, it does not obviously lend itself to a follow-up hit, making OMI a likely candidate for the one-hit wonder list.  But we’ll see.

On the album chart:

• “The Desired Effect” by Brandon Flowers at 1.  Second solo album from the Killers’ frontman, and his second number 1.  Single: “Lonely Town”.
• “Saturns Pattern” by Paul Weller at 2.  His twelfth studio album.  Obviously, Paul Weller doesn’t need singles.  But here’s “White Sky”.
• “Sol Invictus” by Faith No More at 6.  Their first studio album since 1997.  Single: “Superhero”.
• “#1 to Infinity” by Mariah Carey at 8.  It’s a compilation of her number 1 hits, with one bonus track, called, obviously, “Infinity”.
• “Why Make Sense?” by Hot Chip at 13.  Their fifth album, and they graduated into being an albums-only act after the second.  Number 13 is pretty much typical for them these days.  Single: “Need You Now”.
• “Blurryface” by Twenty One Pilots at 14.  Fourth album by an Ohio indie duo, and their first appearance on the UK chart.  Single: “Stressed Out”.
• “The Purple Album” by Whitesnake at 18.  Whitesnake, who were formed by a bloke from Deep Purple, do cover versions of Deep Purple songs.  I know.  Single: “Stormbringer”.
