So at 9.43pm GMT last night somebody somewhere downloaded the ten billionth track to be sold by Apple's iTunes. We don't know who it was or what they downloaded. But we do know that person's iTunes account just got charged up with a ten grand credit, which has to be nice. We thought we'd celebrate this digital music landmark by bringing you ten billion iTunes-related news stories. So, here goes.

Story one: iTunes will start selling recordings of performances of the live heats on the latest series of 'American Idol', with tracks going live the day after each show airs. The Apple store will also announce upcoming themes on the 'Idol' show and publish playlists of the original versions of songs covered on the programme.

Story two: There is a bit of confusion this week as to Apple's policy on sexually explicit iPhone apps. Last week Apple started removing some of the racier apps from its official store, seemingly after complaints that they were easily accessible to children in possession of an Apple phone. But The Register reports that while some have indeed been removed, others still remain. It's not clear if that's because such apps are being removed selectively, or because it's taking a long time to find them all among the 150,000 odd apps in the Apple store. Some also wonder whether a locked 'adult content' strand is now being planned in the app store. Some developers noticed an 'explicit content' tag was temporarily added to the app upload system earlier this week. If all explicit content was to be banned no one would ever select such a tag, so if that became a permanent fixture of the upload platform then presumably Apple plan to have somewhere in their store where such things can be distributed.

Story three: We7's previously reported iPhone app has now been approved by the Apple appy types, meaning it will be available to download from Monday. This will make the online streaming service mobile compliant. As with Spotify, mobile We7 will only be available to premium subscribers. As previously reported, We7's recently launched premium offer retails at half the cost of its Swedish rivals, at £4.99 a month.

Story ten billion: US TV network CBS is reportedly planning to start selling selected TV shows via iTunes in America for a dollar a show, making those programme available at half the current cheapest price point for telly content on the download store. It is thought the price drop is an experiment to see if sales dramatically increase.

And there you have it. This ended up being a very long article, I do hope our blog system doesn't truncate it.
