Amazon wants to launch a music subscription service that would work the same way services from Apple, Spotify and many others work: $10 a month, for all the music you can stream, anywhere you want to stream it.

But Amazon is also working on a second service that would differ in two significant ways from industry rivals: It would cost half the price, and it would only work on Amazon’s Echo hardware.

Industry sources say Amazon would like to launch both services in September, but has yet to finalize deals with major music labels and publishers. One sticking point, sources say, is whether Amazon will sell the cheaper service for $4 or $5 a month.

I can’t imagine a music service that I could only use in one place. One of the things I love about Apple Music is that it is always with me: on my computer, on my iPhone, iPad, in my car, always available.

I like the idea of a cheaper service, that might move me, but only if I didn’t have to sacrifice portability.
