It is ridiculous, to be honest. I am not surprised, since the iPad "PRO" can't even do it.That is an unfortunate gyp for the plus model. Bummer.
Today, I am listening to their "Behind the Boards: Rudy Van Gelder" playlist (Miles, Coltrane, Monk, etc..) that they had in my For You feed this morning. Awesome stuff.
I haven't used Spotify in a while. I was not much of a fan. I much preferred the desktop app (and the apps I could add to it) than the iOS app (that I used 90 percent of the time), which did not have the same features. It is why I ended up with Rdio.
