This is fantastic - Charlie Brooker and Annabel Jones (creators of Black Mirror) did an AMA (Ask Me Anything) on Reddit the other day. Someone asked if they could have the ringtones from Nosedive (rating 1-5 stars generated different sounds). Charlie then delivered in this comment with the links to all 5 Nosedive ringtones. I'm pretty sure I have some specific instances where these will be appropriate, awesome to have them as an mp3.
