On my BB 9790 installed v 0.5.1.2 (according to My World info), v 0.5.1.1.g8d00422e according Spotify itself, quite often items stop playing a couple of seconds (4 or 5 seconds) before their end. This is very annoying. I need to manually advance to the next item every time.
This does happen to both online and offline playing. But it seems to happen mostly with items in offline playlists.
