1/ never had that problem 2/ this is the single best feature of spotify vs the others, I love plugin my android smartphone in my audio system, and to control the music from my ipad, computer. The problem you talk about never happens to me, it shows a popup about if I want to continue here, but only if I go into the app. 3/ I had no problem with that, but it would be better if it uploaded the music to listen on other devices, this is the major pain point about spotify. 4/ what ? only if you ask some playlist to be synchronized it download them and then stop, or are you talking about the fact that it shows the currently playing song on others devices, just swipe out the app, but I am not sure it consume a lot. 5/ I didn't had a lot of problem with the android app
