I would like this also
Personally, and it may just be me, or that I'm not used to it, but I find the Amazon Music program a real confusing mess, that you try some things and can't find the song, but search on different ways and they may find it
Oh, and yes, the ability to select something from the App to play on the Echo would be great.
Honestly sometimes I have to verbally fight almost with the Echo to make it understand what I'm asking for.
I say the track and the group and it can't find it, then I just try the track and it finds it by the group!
I don't like the Free/Pay/Prime/Ultimate tracks all mixed in together, it's all very messy IMHO.
A good example of, I don't know what Amazon are doing.
Jean Michel Jarre Oxygene
It's one album, all the way thru
So far, I've not been able to find a combination of words to tell Alexa to play the album Oxygene by Jean Michelle Jarre
If you look in the music app it's all spread around
If anyone can tell me, how to phrase it in such a way that Echo will play the album as it's meant to be, I'd like to know
