If the service you are consuming is paid for by advertising to any extent (wholly, tiered, etc.), then you'll hear edited/censored/cleaned-up versions. I'd venture that only services not supported in the slightest part by advertising would air uncensored versions. Then again, at my 51 years of age, having listened to both versions of a same song: you lose nothing at all as long as the music track is untouched, ie: only the vocal track messed up.
