When my son had Spotify, he'd shared his a/c details with flatmates or been sloppy with passwords or security. He was with us on a trip, so connected to the sound system in my vehicle to play some music for us all to enjoy - maybe. Someone somewhere was having fun - half way though a track it would switch to what at guess may have been selections from "Bollywood's Greatest Hits". Was very funny - but only the first few times.
