This isn't a one-time occurrence, but has happened multiple times where I hear explicit lyrics in a song not marked explicit.
I don't think it should be an auto-marking due to possible abuse, but there is no option to challenge a decision made by the publisher of music/Spotify through their app regarding explicit rating. There needs to be a mechanism allowing users to challenge the decision.
If I'm playing music and am in a mixed audience, I in no way want to blare "F***" through the speakers. Why not let the consumer help and in doing so help give customers (kids included) more control over what they'd like played?
I've seen threads posted on Spotify but none of them seem to have garnered enough votes to push a decision or get noticed by Spotify devs.
