They don't really want you to submit this as an Idea, they're just giving you the run around. There actually was an Idea posted about this very issue before they posted suggesting to submit it as an Idea. Someone responded to that original Idea that it's a bug, not an idea, so they shouldn't use the Ideas section for it. The original Idea was closed.
Rant aside, I'm with the others. It's absolutely idiotic that a Shuffle on/off setting wouldn't "stick" between music sessions. I can't tell you how many times I've tried to listen to an artist and then just given up and shut it off, because it's playing random songs that I've never heard of. I'm switching to Amazon Music, as it is the same price and doesn't have this issue.
This is not the case for me. My favorite album is "The Stranger" by Billy Joel and anytime I ask Alexa to play the album, it shuffles it instead of playing "Movin' Out (Brian's Song)," which is track 1.
It should default to playing the popular songs when you choose an artist and then shuffle if you request it. The very least they should add an alexa command
"Play popular songs by Oasis"
Right now, it's a disaster and the latest changes have made it even worse. It used to start with the popular song and then shuffle so you could catch it before it started shuffling. Now you can't even do that. It starts in a random location/song so there's no way that I know of to listen to the popular songs.
When I want to listen to a specific album I want to hear that album in the order the tracks are on that album. Not shuffled at all. If I want them to be shuffled or a "popular mix" I should be able to request that from Alexa via my Echo Dot for a specific artist. The DEFAULT setting for Alexa should be to play an album as it was released with the tracks in the proper order as chosen by the artist, producer, or engineer.
Premium family member and a fresh owner of several Echo dots. The auto shuffling is so annoying and stupid, that if it's not fixed in few weeks time, I'll cancel my subscription. There is always Amazon Premium after all.
