The post-Top Gear careers of Jeremy Clarkson, Richard Hammond and James May don’t really fall under Music Ally’s remit. Well, not usually. The trio are debuting their new motoring show The Grand Tour on Amazon’s Prime Video service this week, and alongside the launch Amazon is cutting $20 off the cost of a Prime membership in the US for anyone who signs up today – down from $99 to $79. A similar price cut is happening in the UK. How does music fit in to this? If The Grand Tour succeeds in attracting a new influx of Prime subscribers, they’ll also be potential listeners for Amazon Prime Music (and, in turn, potential upgraders to Amazon Music Unlimited). It’s one of Amazon’s advantages in the digital music ecosystem: any improvements (new TV shows included) that it makes to Prime can widen the funnel into its music-streaming services.
