The evidence suggests otherwise. The music business has changed radically from the model you set out. It is no longer enough for an artist to demand their record company spend money on promotion & wine & dine radio dj's to play a track. Morrissey's new single has been played sufficiently for the UK public to decide if it's a track they want to add to their collections. The evidence is they are ignoring it as it isn't even in the Spotify Top 200 chart even though it's free to hear! It's also no longer in the industry orchestrated Viral chart which suggests the attempts to win over the radio stations was a short-lived effort.
Ed Sheeran's songs are played non-stop by vast numbers of people. He is one of the few artists who can still sell physical CDs as he has the brand power to have them in petrol stations and supermarkets for legacy CD equipment in cars. He is immune to reviews as his audience know the industry is full of people trying to foist legacy hype such as Morrissey on to listeners. In the era of Spotify, it's viral streaming that drives album sales for a select few artists. Morrissey isn't one of them.
The evidence suggests that you could play STDIB non-stop on UK radio but nobody would ever listen to it again. For free. On Spotify and other streaming services. Why? Because these 'clueless consumers' as Morrissey called them think it's not worth listening to again.
You could plaster every billboard in the UK with the cover of LIHS and people would ignore it. The 'clueless consumers' aren't ast stupid as Morrissey thinks. His decades long posturing as a 'radical artist trying to break into the mainstream media' has been exposed as nonsense. He is a Singing Troll and the British Public are not interested. At least not in the numbers that Morrissey bizarrely imagines he is 'entitled' to. His conspiracy theory must now shift from the record labels, radio stations and print media to the music listening public. Why are the music listeners of the UK refusing to play his new single even when it's free on Spotify? Should be amusing to watch his contortions to explain that one!
