Simple question - How to close Spotify on Android?

[Denial94]

Hello

I'm using Premium Spotify on my LG L9 and I have around 1000 songs on my SD Card. After listening music I'm closing app by Android Task Manager  (something like here http://puu.sh/fxkP5/3b219a8908.jpg (it's not my screenshot )). When I want listen Spotify again It's says cannot find my SD card so I have to restart my phone. But after restart, playlists are unavailable and then I must connect again to internet. 

I think I'm doing something wrong with closing Spotify or they just should add quit button. Any help?

Tried restarting, removing, installing, reinstalling etc. Spotify is greedy for money so they don't care about customers (like with their ugly black design) so I'm trying looking for help here.

Don't use an android task manager, they do nothing beneficial.

Yeah a task manager force closes things like on windows so it doesn't give the application the correct warnings so this is not a bug as such more a problem with task managers. Can you not just Swype it away from your multitasking menu? That should close it enough so that its not laggy.

Hope this helps
