On the other hand, Pandora, it feels like has recently been making picks that somewhat mush your likes and seeds from all your stations together.
While this is true it's ridiculous how often, at least for me, Spotify creates a playlist with songs that I've listened to hundreds of times already.
At least 70% of my discovery weekly playlist is a song I've already heard. If I create a "Similar playlist" it stuffs it with songs that I listen to regularly. It's deeply disappointing.
While I love the concept of Spotify, I'm certainly not going to pay for it and eagerly waiting for competitors to be available in my regions.
It was easy when I created trushuffle some 8 yrs ago (before Spotify aquired echonest) and it should be even easier for a multi billion company.
