Searching and playing music, and facebook integration (with a dll override: see other comments).
What does not
Nothing I tested seemed to fail. I never did install Windows Media Player, so I strayed away from pressing the "Windows Media Player" option in the left sidebar.
What was not tested
Creating playlists and features only available as a premium user.
To keep the application from crashing for accounts with facebook integration, obtain winhttp.dll, dump it in wine's system32 folder and add a dll override for spotify in winecfg.
