The more I use Spotify, the more frustrated I get with it. Two things in particular are beyond annoying: the random and automatic movement of my library from SD card to device storage; and continual redownloading of tracks. The latter cannot be stopped unless you select "Remove Download", which 'undownloads' the entire playlist. Doesn't matter if you don't delete your cache, Spotify will do it for you and change the storage location without telling you. And I pay Premium for this rubbish.
