We’ve been using Prime music a fair amount recently with our echo dot, the kids like streaming lots of pop stuff, I listen to various play lists when cooking, me and the missus keep picking various old songs and albums from the 80s/90s/00s to reminisce over our Yoof, it’s not so bad and by default you also have old purchases as digitised content, stuff you’ve bought before i.e. it’s got a couple of slightly obscure albums against my account that I bought from Amazon on CD well over a decade ago, I can download the MP3 files for them too…
You can set up an Echo to stream from Spotify but only if you have a full paid Spotify sub. With prime it’ll let you stream quite a bit for free, without adverts and you can compile playlists too if you want, when you try to play something not included in prime it will simply tell you it’s not covered by your Prime music sub and ask if you want to pay for the single song or upgrade to the full music unlimited sub…
Basically they’re treating music like they have film and TV, there’s a fair bit covered under the Prime banner, and a bit more available if you are willing pay more…
I’d pay for one or the other, but certainly not both and it would depend on what devices you have to stream with, at present We’re happy enough with Spotify Free (Advertising and default shuffle function) and Prime music via the Echo dot…
