Quarteto Maogani, a fantastic brazilian guitars group, has its different albuns registered in spotify under three different names: Quarteto Maogani, Maogani Quartet and Maogani. So it's impossible, for example, to hear the complete group works in a single random reproduction session. This is a flaw in Spotify's artist database that should be corrected.
