I don't listen to enough music for £10 a month to be worth it to me, but £5 felt justifiable.
Using Siri as the only interface is an awful experience, but it's an awful experience that cost half the price of the usual one, and since I only used it on my HomePod mini anyway, the Voice plan was sufficient.
Once it stops working I guess I'll go back to YouTube for music discovery, combined with buying CDs/DRM-free-M4As for the two or three albums I buy a year.
I've been using a 4th-gen iPod to make my YouTube videos for the last few months and if it had Bluetooth I'd happily use it instead of even my iPhone.
